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.

'Go-To Guy' Kanitz Sets Selfless Example in Helping Make St. Francis Sports Go

Traverse City has had a few head football coaches named Kanitz.
But Mike Kanitz has no interest in becoming a head football coach. In fact, no interest in being a head coach of any sport.
So far he’s worked for nine head coaches. He’s seen what it takes to be a head varsity coach and he’ll stay where he is, which is pretty much anywhere there is a high school sporting event.
Kanitz spends his days and nights dedicated to the Traverse City St. Francis student-athletes, staff, administration and Gladiators community. He is the junior varsity girls basketball coach, volleyball game manager, volleyball announcer and volleyball scorekeeper, football press box manager, and the Glads’ soccer game manager. Additionally, as director of basketball operations at St. Francis, he finds himself at the scorer’s table for boys basketball games.
The volleyball, soccer and football duties are performed at every home game. He doesn’t take a paycheck for any of it. If the school does pay for his services, he promptly donates the funds to the source.
The soft-spoken and renowned St. Francis supporter is not the slightest bit interested in getting any recognition for his efforts.
Tonight he’ll run the Thirlby Field press box as the Gladiators host Ogemaw Heights. And, he’s ready for the Glads’ first home volleyball match Sept. 8.
“He is one of those unique people that shies away from the spotlight — he is a pure servant, said Aaron Biggar, St. Francis’ athletic director. “He doesn’t want any accolades or anything like that.”
Kanitz’ father, Hugo Kanitz – who also went by Mike all his life – was the head football coach of Traverse City St. Francis during the 1960s. Another Kanitz, Dutch — not related to the father-son combo —was at the helm of the Traverse City Central High School football program.
Mike Kanitz finds himself regularly receiving phone calls and letters from former players intended for the Kanitz coaches. He has to explain he’s not the deceased Central coach, nor his father. And he’s glad he gets to pass on positive feedback to his father, also a former athletic director for St. Francis.
“My grandmother said, ‘Never call him Hugo – his name is Mike,’” Kanitz said. “Don’t ask me where it came from, but he was Mike his whole life.
“I am junior in most people’s minds,” Kanitz went on. “Traverse City was a small town back then; to have two Coach Kanitz was confusing.”
His father now lives in Traverse City after retiring as a teacher and professor. The son enjoys picking his brain.
“I am blessed to still be able to run stuff by him (because) that’s really where I got my coaching start,” he said. “I used to get calls after coming back to Traverse City and the callers would say, ‘Is this Coach Kanitz?’ and I started to catch on that these were his former students.
“I don’t think my dad ever knew the impact he was having on kids,” Kanitz continued. “I don’t think coaches really know what an impact they have on kids.”
Hearing from his father’s former players helped shape his coaching.
“It made me realize as a coach you have the ability every time you open your mouth to either hurt a kid or help a kid,” he said. “So helping a kid is my desire.”
Officials, media and visiting coaches for many sports have noted Kanitz’ demeanor and contributions. They also know he’ll do anything to make sure they have a good experience at St. Francis.
Among other things, Mike reportedly once became a makeshift tailor when a basketball official showed up without his referee pants. Mostly using safety pins, a borrowed pair of pants went from 2XL to large in time for tip-off.
“Mike Kanitz should have a name tag that says, ‘Nicest Man on the Planet,’” said former St. Francis AD Tom Hardy. “Mike is the perfect representative that you can have for any event at school.
“He greets every team, official, and spectator with such grace and compassion, which leads to a very positive experience for all involved,” Hardy continued. “Mike has volunteered too many hours to count at basketball and soccer games as a game manager and coach.”
Hardy believes all sports fans need to follow Kanitz’ lead.
“Mike Kanitz is the example of how people should treat each other at any athletic event,” he said. “You truly would have to look long and hard to find a more compassionate and caring individual, and I would challenge anyone to find a person that has a negative thing to say about him.”
Barb Becket, a longtime MHSAA official and assignor, has similar views of Kanitz. She’s worked with him while he’s served as a coach, game manager and during community activities through her role with the Grand Traverse YMCA.
“Mike is the go-to guy,” she said. “He is a servant in the true sense of the word.
“Besides being the go-to guy for coaches, admin, and players, Mike also acts as the liaison between the sports officials and the sports participants,” she continued. “Mike handles his responsibilities with grace, humility, common sense, and accountability.”
Kanitz’ favorite sport to play is baseball, but his favorite sport to coach is basketball. After graduating from Alma College where he competed in track & field, he was thrilled to move back to Traverse City to start a family with his wife Marcy, a Traverse City obstetrician.
The couple’s three children graduated from St. Francis, and Kanitz first focused on elementary baseball. He was able to step away from his pharmaceutical career to step in and fill pretty much any need the St. Francis community had.
Kanitz points to his wife’s passion for caring for women as a motivator for him to get more girls involved in sports and receiving the benefits they provide.
“Marcy spent her whole life taking care of women,” he said. “So she sees the side effects of women not being given opportunities.
“So we’ve got to correct that stuff.”
Kanitz’s first job was as a water boy, along with his siblings born to Hugo and Margo Kanitz. If he ever can’t coach or serve in other capacities for the Gladiators, he hopes to return to the very first job he had as a preschooler.
“I am sincere when I say I started as a water boy, and I am going to finish as a water boy,” Kanitz said. “I am very blessed and I am thankful for the life I’ve had here in Traverse City.
“I am thankful for the school allowing me to be a part of it.”
