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.

Frankfort Hoops Staff Bolstered by Past Stars Giving Back in Banktson, Kreski

Veteran Frankfort girls basketball coach Tim Reznich will have a couple of true superstars on his bench this winter.
They don’t have MHSAA eligibility remaining, but they should really help the Panthers. They’ve used up their college eligibility as well.
They are Lindsey (Pettit) Banktson, a 2008 graduate of Portland High School and all-state forward, and Presley (Hudson) Kreski, a 2014 product of Wayland High School and all-state guard. And, they are now serving as assistant coaches for Frankfort.
Banktson has been on Reznich’s bench 10 years, and Kreski is headed for her first at Frankfort. Kreski has been on women’s basketball coaching staffs at Western Michigan University and Central Michigan University since her playing days.
“I have always felt very fortunate in my situation at Frankfort,” Reznich said. “I have felt like we have always been able to provide our players with the resources and opportunities to excel at basketball, if that is what they wanted to do.
“When Lindsey came those resources increased, and now adding Presley to the mix just brings everything over the top,” he continued. “Our players are already starting to realize it.”
Kreski, who will be teaching health and physical education at Frankfort, and Banktson, now a physician assistant with Crystal Lake Clinic, are excited to work together and with Reznich this winter as he begins his 22nd season at the helm of the Panthers.
“I’ve loved coaching with Rez the past 10 seasons and am just as excited for season number 11,” said Banktson, who went on to play basketball and softball at Ferris State University. “Every year, the night before our first day of practice, is always like Christmas Eve for me.
“I can’t sleep and I can’t wait for my alarm to go off to head to the gym to start our 2-a-days,” she continued. “I am so grateful to coach with Rez and learn from him.”
Kreske too is eager to work with Rez after getting involved with the Panthers in summer ball.
After Wayland, Kreski went on to an illustrious playing career Central Michigan where she won the NCAA 3-point contest in 2019. She also played with the Seattle Storm of the WNBA before playing professionally overseas in Poland.
“I am really excited to be at Frankfort and helping the team out,” Kreski said. “The girls work really hard and want to get better.
“Tim is a great coach, and I am looking forward to working with him and sharing my knowledge of the game as well as learning from him.”
Frankfort is coming off a District championship in 2022 and a District title loss to eventual Division 4 champion Glen Lake in 2023.
Reznich says the Panthers have already noted keys to success just by being around Kreski and Banktson. Reznich, who guided Frankfort to back-to-back Class D championships in 2005 and 2006, admits he may have softened up a bit on his players over the years. Conditioning will be a top priority this year.
“They (Kreski and Banktson) have the first-hand experience of the benefits of pushing yourself hard and not cutting corners,” Reznich said. “Our players will be in the best shape of their lives when those two are finished with them.”
And Banktson is happy to pass on her high school experience to the Panthers. She graduated in 2008 as the Lansing State Journal’s “Female Prep Athlete of the Year” after shining in three sports and leading Portland to the season’s final weekend in two.
“As a player, high school athletics taught me a lot about hard work and dedication,” she said. “High school sports taught me that you have to put in the extra work if you want to be great.
“You have to be in the gym getting extra shots outside of practice, you have to be at the field getting extra reps on the weekends,” she continued. “If you work hard and give everything you’ve got to develop your game, you will be successful.”
Kreski recalls fondly her high school days working hard and having fun with her friends and teammates, along with making deep runs in the tournament.
“High school sports is the truest form of competition,” Kreski said. “It starts with a community who supports everyone from a young age and involves all the friends and family you grew up with.
“High school sports help guide young people into leaders, teaching them how to work hard and be disciplined.”
Kreski led CMU to Sweet 16 her junior year. She is the all-time leading scorer at CMU (2,309) and career assist leader (643). Central won the Mid-American Conference three times during her days with the Chippewas. She married Gage Kreski after that chapter of her career was done.
Banktson met her husband Max Banktson at Ferris State, where he played football. They moved to Frankfort, where Max was born and raised. They have a 3-year-old son named Briggs and a 6-month old daughter named Landyn.
Both Reznich and Banktson express respect and appreciation for their coaching together. They’ve been on the same page with game plans and scouting reports, and they expect it will continued with Kreski aboard.
“Rez and I really work well together,” Banktson said. “He has always respected me as a player and coach and has given me so much autonomy with our teams.
“He is always open to my input when it comes to running certain drills in practice, putting in new offenses, or adding defensive schemes,” she continued. “He trusts me to handle our subbing during games.”
Reznich agrees.
“I have always appreciated Lindsey’s perspective on what the girls are doing on the court,” he said. “It is going to be a lot of fun and exciting to add Presley’s ideas.
“We have always treated the regular season as practice for the tournament, making adjustments and tweaking things,” he continued. “I can’t wait to see the end product this year.”
Banktson was a three-sport, four-year varsity player at Portland earning a combined 12 varsity letters in basketball, softball and volleyball. She helped the Raiders win league, District and Regional titles. Her teams reached MHSAA Semifinals for softball twice and basketball once.
It doesn’t take much to get her back in game mode.
“I can still remember the feeling of adrenaline getting ready in the locker room with my teammates, running out to our warm up music, and battling on the court each game,” she said. “I am thankful for my teammates who, when on the court, were so unselfish. We just wanted to win.”
She hopes to continue to instill greatness in the Panthers.
“I always tell the girls, ‘We were tough’ — not just physically but mentally,” she said. “We had a type of swagger – we played like we knew the bullseyes were on our back, and every game we had to fight to stay at the top.
“We took pride in wearing that Portland Raider jersey,” she continued. “I just want to instill that same mental toughness and swagger into my girls here at Frankfort.”
Having a pair of women who played now coaching and serving as mentors is beneficial on a personal level as well.
“I feel like I can relate to players on a personal level,” Banktson said. “I always try to be a good role model for them and someone they can come to with anything.
“I’m their biggest cheerleader but also not afraid to hold them accountable and help steer them down the right paths of life.”
And Banktson has learned how she might have coached herself.
“I would push myself to continue to work on my right hand, because everyone in the gym knows I’m a lefty,” she said with a smile.
