Soccer, Hoops Next to Seed Using MPR

As the topic of seeding for MHSAA Tournaments continues to swirl in the air of numerous committee meetings on an annual basis, one of the primary concerns continues to focus on the simple question: “How?”

The MHSAA for years has been working behind the scenes on potential formulas which could best be used as a standardized tool to assist in measuring strengths of teams in a given sport.

This spring, the MHSAA introduced the Michigan Power Rating in the sport of Boys Lacrosse. The Representative Council approved limited seeding beginning in 2019-20 for girls and boys soccer and girls and boys basketball, and MPR will be the metric to determine which two teams must be seeded on opposite sides of District brackets in those sports.

“The boys lacrosse tournament has been seeded since it was added as an MHSAA-sponsored sport in 2005. The seeding is done by committee based on several criteria, one of which was statewide power rankings generated by a third-party website. In the Fall of 2018, that website ceased operation – it was the perfect opportunity for the MHSAA to develop its own data-driven, purely objective ratings system and incorporate that data into the seeding criteria,” said Cole Malatinsky, administrative assistant for the sport.

“The benefits of the new MPR system have been already mentioned – it is MHSAA controlled, simple, objective, and transparent, and it can be used by other MHSAA sports in the future.”

MPR is a computer rating formula similar to the popular RPI rating. MPR provides a way to measure a team’s strength relative to other teams, based on games played against other MHSAA tournament teams, largely on the strength of their opponents’ schedules. MPR is purely objective using only the game results listed on MHSAA.com – there is no subjective human element.

What is the basic MPR formula?

MPR is calculated using wins, losses and ties for games played between teams entered into the MHSAA tournament. The final MPR number is 25% of the team's winning percentage, plus 50% of its opponent's winning percentage, plus 25% of its opponent's opponent's winning percentage.

MPR = (.25 x W%) + (.50 x OW%) + (.25 x OOW%)

The MPR formula can be applied easily to other MHSAA team sports.

What game data is included in the formula? What game data is not?

MPR looks only at results between opponents entered into the MHSAA postseason tournament. Wins, losses and ties in multi-team shortened game tournaments (lacrosse, soccer) also count. Forfeits also are counted as wins and losses.

MPR does not use the specific scores of a game or the margin of victory in a game. The location of a game is not included in the MPR formula, and the formula weighs results at the beginning of the season the same as results at the end of the season. Scrimmages are not included.

Why use the MPR formula?

Different rating systems have been used in the past or have been recommended to the MHSAA. We wanted to have a rating system where the data was controlled and stored in house and could be used for any sport featuring head-to-head competitions.

With its own rating system the MHSAA also can control the different components of the formula, thus keeping the tenets of scholastic competition at the forefront (like not including margin of victory in the formula). Finally, by listing all scores and team schedules online, as well as showing the MPR calculator on each team schedule page, the ratings are transparent and can be replicated easily.

CALCULATING MPR

What are the detailed components of the MPR formula?

You need three numbers to calculate your MPR: winning percentage (W%), opponent’s winning percentage (OW%) and opponent’s opponent’s winning percentage (OOW%).

How do you calculate winning percentage (W%)?

Divide the number of wins by the number of total games played. A tie is worth half a win. For MPR purposes, find the winning percentage against all teams that will play in the MHSAA tournament (MPR W%). Games played against out-of-state teams, varsity “B” teams, junior varsity teams, non-school club teams, and any other non-MHSAA tournament participants should not be included when calculating winning percentage. W% should be an easy number to calculate.

How do you calculate opponent’s winning percentage (OW%)?

Average the winning percentages of a team's opponents. When calculating the winning percentage of a specific opponent, use the opponents "Adjusted Winning Percentage" (ADJ W%). Adjusted winning percentage eliminates all games the team played against that opponent (as well as its games against non-MHSAA opponents).

For instance, if the team beat an opponent with an overall record of 4-1, use a record of 4-0 (1.000) for that opponent. If the team lost to an opponent, use a record of 3-1 (.750). Find the ADJ W% for all opponents, and then take the average. If a team plays an opponent team twice, that opponent’s ADJ W% will be counted twice.

OW% is not calculated via the combined record of the opponents; instead take the average of all opponent’s winning percentages.

How do you calculate opponent’s opponent’s winning percentage (OOW%)?

Use the same process described above, except calculated for the opponents of a team's opponents. This number is much harder to manually calculate, so the OW% for every team is listed on the MPR page of the MHSAA website.

Again, simply take the average of all opponent’s OW%.

How often is MPR calculated?

MPR is calculated about every five minutes. Enter a score and a minutes later the team MPR and the MPR of all the team's opponents will update.

How much will my MPR change throughout the season?

You will see wild MPR swings in the beginning of the season, but after about 10 games played your MPR will start to level out. At 20 games played you will see very little movement with each additional game played.

My score is missing. How can it be added?

This is a crowd-sourced system. Any registered user of MHSAA.com can add a missing score. ADs, coaches, parents, students and fans all can login and enter a score for any game.

What are some common errors when calculating MPR?

When calculating your team’s winning percentage, only include games against MHSAA-tournament teams. When calculating your opponent’s winning percentage, don’t include the games they played against you. When calculating ties, count the game as a half-win and half-loss.

What happens if a game is cancelled?

Because the MPR system works off of averages, it will not make a difference in the final MPR if a game cannot be rescheduled. It would not penalize, nor benefit, any team involved in that scenario.

USING THE WEBSITE

Where can I find game scores?

A list of statewide scores for all sports can be found in the MHSAA Score Center. To find a schedule for any team click on “Schools & Schedules” in the top navigation bar, search for the school, then once on the school page click the sport. You can also see a list of all schools (with links to schedules), on the statewide MPR list.

“We continue to have great success in score reporting for varsity boys lacrosse contests. While we state that schedule submission and score reporting to MHSAA.com are required, athletic directors and coaches understand that in order for MPR data to be accurate, we need consistent and accurate score reporting,” said Malatinsky. “MHSAA.com is now the primary site for high school boys lacrosse schedules, results and ratings in the state.”

How should I use the statewide list of teams and MPR?

Linked to the boys soccer page (and eventually to be added for both basketball pages and girls soccer) is a statewide listing of all Michigan Power Ratings (MPR) for teams entered into the MHSAA postseason tournament for that sport. Linked on the MPR page is an explanation of the District draw formula, describing when and how teams will be placed on the bracket.

The MPR data updates every five minutes. Click on the column headings to sort the data. You also can use the drop-down menu to show teams in one Division, or type a District number in the box to filter teams for that District (Region for boys lacrosse).

You also can click on any school name to go to its schedule page.

How do I read the school schedule page?

The schedule at the top of the page shows the date and opponent for all scheduled games, and results for games already played. If results are missing, click “Submit Score” to add a game score.

Below the game schedule is the MPR Calculator. The calculator is split into three sections. The first section shows the three MPR component scores for the team, as well as the team’s current MPR score. The second section shows the MPR information for the team’s opponents – specifically, for the opponents the team already has played (actually, for games where scores have been submitted). Only these games are included in the MPR calculation.

The third section highlights future opponents. The MPR data for future opponents are not used in the MPR calculation for the team.

Record-Setting Coach, Championship Program Leader Selected for 2024 WISL Awards

On the basketball court, no woman in Michigan high school history has led her team to more victories than Bloomfield Hills Marian’s Mary Cicerone. And few schools have stacked more championships over the last decade than Ann Arbor Pioneer under the guidance of athletic director Eve Claar.

To celebrate those accomplishments, and more significantly their impacts on thousands of students over decades in those leadership positions, Cicerone and Claar have been named the 37th and 38th recipients of the Michigan High School Athletic Association’s Women In Sports Leadership Award.

Each year, the Representative Council considers the achievements of women coaches, officials and athletic administrators affiliated with the MHSAA who show exemplary leadership capabilities and positive contributions to athletics. Cicerone and Claar will receive their awards during this year’s WISL Conference, Feb. 4-5 at the Crowne Plaza Lansing West.

Cicerone retired from coaching the Bloomfield Hills Marian girls basketball team after the 2021-22 season with a record of 707-233 since taking over the program in 1983 – making her the fourth-winningest coach in MHSAA girls basketball history, and the winningest woman to lead a program.

She guided the Mustangs to six Finals championships, in Class A in 1988, 1992, 1996 and 1998 and back-to-back in Division 1 in 2014 and 2015. Her teams also won 19 Catholic High School League Central division championships, 20 overall CHSL League titles and reached the MHSAA Semifinals seven times, also finishing Class A runner-up in 1997.

“Mary Cicerone is a legend because she’s won hundreds of games and many championships, and those measurables of her success speak for themselves,” MHSAA Executive Director Mark Uyl said. “But her commitment to her teams, her sport, and leadership in women’s athletics as a whole contributed just as significantly to her tremendous legacy.”

In addition to receiving several local and statewide coaching awards over the years, Cicerone has been inducted into Halls of Fame by the University of Detroit Mercy (2007) as a player and as a coach by the Catholic High School League (1998), Basketball Coaches Association of Michigan (2017) and Marian (2022).

She has served as an officer for the Catholic League Women’s Coaches Association and in 2009 received the CHSL’s Ed Lauer Person of the Year Award.

“Being a young girl wanting to play all kinds of activities, we never had much opportunity and I participated in whatever I was able and just felt like that was something that was important to me, my friends and everybody I was associated with was always part of the same group,” Cicerone said. “I felt like (advocating for women’s sports) was something I should do because it was so important for me, and I appreciated everything everybody did for me and my friends to be able to play.

“It’s not something I needed to do – just something I wanted to do. I stepped into that role, cherished it, worked really hard at it, and hopefully made great memories – for me, for sure – and for others.”

Claar is in her 21st year as an athletic director, and over the last decade has guided one of the state’s largest athletic programs in terms of both programs and student-athletes, with 36 varsity teams and nearly 1,110 participants. The Pioneers have had ample local and statewide success during her tenure, including claiming 16 MHSAA Finals championships across seven sports over the last eight school years (including this one). Most recently, Pioneer tied for most Finals championships among Lower Peninsula schools in 2020-21 with four, were second in 2021-22 with four more, and last school year tied for most in the Lower Peninsula again with three titles.

Claar began in athletic administration as Pioneer’s assistant director from 2003-06, and she became athletic director at Bloomfield Hills Lahser at the start of the 2006-07 school year. She took over the program at Ypsilanti Lincoln as athletic director in 2009 before returning to Pioneer in 2012.

“Eve Claar continues to show the way for her programs to succeed on the field while keeping in mind the big picture of what’s important in school sports,” Uyl said. “She’s invested in providing the best experiences for Pioneer’s student-athletes, and athletes competing throughout the Southeastern Conference, while also providing support to AD colleagues and coaches who look to her for leadership and expertise.”

Claar has served as the Southeastern Conference secretary since 2009 and is the league’s sport director for softball and field hockey. She has been president of the Michigan Field Hockey League since 2018 and has served on several MHSAA sport and site selection committees and as part of the MHSAA/Farm Bureau Insurance Scholar-Athlete Award selection committee. Before becoming an athletic director, Claar worked five years in the Detroit Pistons/Detroit Shock community relations department.

She was named a Regional Athletic Director of the Year in 2019 by the Michigan Interscholastic Athletic Administrators Association (MIAAA). In 2021, she helped found the Southeastern Conference’s Women in Sports Leadership Conference for student-athletes from the league’s 14 schools.

“I started with (longtime Pioneer AD) Lorin Cartwright before me, and she was always a mentor for me. I’ve always had female leaders and mentors whether in sports for high school, over to Pioneer, with the Shock with Nancy Lieberman – I’ve been around amazing female leaders,” Claar said. “I feel at this point, 21 years into doing this, now it’s upon me to do the same. I’ve been honored when I’ve had other athletic directors reach out, other female ADs ask for support, and I’ve been able to give the support that (my mentors) gave me.”

Cicerone is a 1978 graduate of Coopersville High School, where she was a basketball all-stater and ran track, and she then starred on the basketball court at Detroit Mercy, leading the Titans to three Association for Intercollegiate Athletics for Women (AIAW) state titles and graduating as Mercy’s all-time career assists leader while earning a bachelor’s degree in education. She won the 1982 President’s Award as U-D’s most outstanding female student-athlete.

She taught primarily physical education at Marian beginning with the 1983-84 school year through her retirement 39 years later, and also coached track & field for a season at the start of her teaching career.

Claar is a 1991 graduate of North Farmington High School and earned her bachelor’s degree in business administration from Central Michigan University and master’s from Detroit Mercy. She received a teaching certificate from Wayne State University and education leadership certificate from Eastern Michigan University, and earned her certified athletic administrator (CAA) designation in 2008. Claar played basketball, volleyball and softball at North Farmington and was a BCAM Miss Basketball Award finalist in 1990. She continued as a standout at CMU, finishing her playing career in 1995, and remains among the most accomplished 3-point shooters in program history. She also served as a graduate assistant women’s basketball coach at U-D for two seasons.

More than 800 participants – mostly female high school student-athletes from across the state – have registered to attend this year’s sold-out WISL Conference, the 26th in the series that remains the first, largest and longest-running program of its type in the country.

The opening address Feb. 4 will be presented by Cathy George, the all-time winningest volleyball coach in Michigan State University history and the first head coach of the newly-created Grand Rapids Rise professional volleyball franchise. Current MSU volleyball coach Leah Johnson will speak during the morning’s general session Feb. 5 on the conference’s theme “Share the Vision” – she finished her second season leading the Spartans in the fall after coaching Illinois State University from 2017-21 and taking ISU to the NCAA Tournament her last four seasons before leaving for East Lansing.

Several workshops will be offered over the two days, with topics including coaching, teaching and learning leadership; sports nutrition and performance, and empowerment and goal-setting. Presenters are accomplished in their fields and represent a wide range of backgrounds in sport. A complete itinerary is available on the WISL page.

The first Women In Sports Leadership Award was presented in 1990.
