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.

Significance of Historic Run, Relationships Formed Live On for 1973 Unity Champs

It has been more than five decades, but Kim Hansen and Marcia (Visser) Beutel can still recall certain moments from a historic night in mid-December when their Hudsonville Unity Christian girls basketball team accomplished a tremendous feat.
On Dec. 15, 1973, at East Kentwood High School, the teammates helped the Crusaders win the first MHSAA Girls Basketball Finals championship in Class B.
Unity Christian defeated Saginaw MacArthur 49-45 before a crowd of 1,000.
“i just remember the team, the bus ride out there, and I remember just how excited we were to be together and what we had accomplished as a group,” Hansen said. “Our parents and friends were such big supporters through the whole process, and when I think back I see faces of pure joy.”
A total of 629 schools participated in that first tournament, which like now lasted three weeks and was divided into four classifications.
Cindy Masselink scored 17 points and Deb Aukeman added 16 points to lead the Crusaders to the championship win.
“For us, it was an excitingly significant day because we had been working hard throughout the season, and we, as women, could be the first winners of a state championship for our school and the state,” Beutel said. “A lot of us had been playing together since the sixth grade, and that camaraderie, that friendship, that teamwork and the work we had put in was going to end with a state championship.
“We were very blessed to be there, and we also knew that we were pioneers and trailblazers in the game.”
The Crusaders consisted of 11 girls, three managers and head coach Susan Contant.
An interesting sidenote from the Class B title game: As the home team, Unity Christian was to wear white uniforms. But the Crusaders didn’t own those.
“There were limited resources for women's sports back then so we had to wear the boys uniforms for the state championship,” Beutel said. “They didn't fit well so we had to wear T-shirts underneath them.”
One thing the 1973 squad possessed was size, which proved to be a benefit as the 3-point shot didn’t yet exist.
“We took each tournament game as it came to us and just kind of did our thing,” Hansen said. “I look back at our pictures, and we were huge. We had a starting five of 6-foot plus, and we were a big team. That definitely worked in our favor, and I really don't think that we were going to be denied.”
Beutel and Hansen, both 69, are organizing a night to recognize this special group of women.
It will take place Dec. 11 during a Unity Christian girls and boys varsity game night.
“We are all much older and lives have happened and we are in different places, but I’m hoping that many of the teammates will come back for that,” Hasen said. “I know our head coach and her husband are going to come back for that, and I think that is just amazing. I haven't seen Sue since 1973.
“I got to see some of my teammates when we were recognized at Central Michigan for the 30-year anniversary, and I’m looking forward to seeing who is going to be able to make it and hoping that many do.”
Beutel lives in Toronto with her husband, Robert. She recently visited her old high school.
“They had a list of all the state championships on the wall, and the first one was us,” she said. “That was very emotional for me to see that, to see that recognition.”
Beutel met her husband at the University of Michigan, and they had three kids. One of their daughters, Sophie, played Division I basketball at Brown.
Beutel moved to Toronto in 1987 and coached basketball in a recreational league while helping grow the game. She was president of the Toronto Basketball Association, which has surged to 1,000 athletes.
The country needed to push for basketball representation and now has the NBA’s Toronto Raptors and the Toronto Tempo, currently playing its inaugural season in the WNBA.
“Back then it was a hockey country, so I had to search for basketball in Toronto,” Beutel said. “I got involved in it and expanded it on the girls side and always coached my kids.”
Now retired after a career as a health care executive, Beutel and her husband love adventures and have traveled to several countries. “There is so much more to experience in life,” she said.
While she stays active by playing tennis, cycling and kayaking, Beutel also plays clarinet in a band and volunteers at a cancer support group as a peer counselor after enduring two bouts of breast cancer.
After high school, Hansen played four years of basketball at Grand Valley State University before being drafted by the San Francisco Pioneers of the Women’s Professional Basketball League.
She played there one season before being traded to the Chicago Hustle. She also spent time with the Minnesota Fillies before the league went bankrupt and disbanded in 1981.
“I think I made $7,000 for my salary and the season was very short, but it was such an amazing experience and San Francisco was a very good franchise,” Hansen said. “They had good ownership and we flew all over the place and stayed in really nice hotels. They had a good practice facility, and we were treated really well.”
Prior to a game scheduled in Chicago on March 21, 1981, Hansen and her Fillies teammates walked off the court before the starting lineups were announced in a protest over unpaid salaries.
“We planned to do our warm-up, go back to the locker room and then get back in vans and drive back to Minnesota because we weren’t getting paid,” Hansen said. “That was our way of showing that we were not happy with ownership and the only way that we could make a stand.”
Despite the disbanding of the league, Hansen said lifelong relationships were formed.
“The beauty of playing sports is relationships, and even relationships that we developed at Unity are still so strong, and relationships I developed while playing pro ball are still very active and to me that is the beauty of playing sports,” she said.
After the WPBL, Hansen went to graduate school at Lamar University in Texas and eventually became an educator and coach at several colleges and high schools, including Wichita State and North Central College (Ill.).
Her final stop was Cleveland Heights High School, where she coached and taught physical education and health. She lives in Kirtland, Ohio, and retired from teaching and coaching in 2024 although she still works part-time in the transportation department.
“I love coaching and I always loved practice,” Hansen said. “I just finished working with four seventh-grade boys and helping them with fundamentals and skills. I just enjoy that part of it so much.”
