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.

High School 'Hoop Squad' Close to Heart as Hughes Continues Coaching Climb

Jareica Hughes had a Hall of Fame collegiate basketball career playing at University of Texas-El Paso and has played professionally overseas, but her most prized possession is something she earned playing high school basketball in Michigan.
A standout at now-closed Southfield-Lathrup High School during the early-to-mid 2000s, Hughes proudly displays a signature symbol of Lathrup’s Class A championship team in 2005.
“I have my state championship ring on me right now,” said Hughes, now an assistant head coach for the women’s basketball program at UTEP. “I wear this ring every single day. Not so much for the basketball aspect. Inside of the ring it says ‘Hoop Squad.’ It’s more the connection I’ve had with those particular young ladies. Friends that I’ve known since I was kid. Every once in a while when we talk, we go back in time.”
Believe it or not, Hughes and her high school teammates next year will have to go back 20 years to commemorate a run to the title that started when they were freshmen.
It was a gradual build-up to what was the first girls basketball state championship won by a public school in Oakland County. Lathrup, which has since merged with the former Southfield High School to form Southfield Arts & Technology, remained the only public school in Oakland County to win a state girls basketball title until West Bloomfield did so in 2022 and again this past March.
Lathrup lost in the District round to Bloomfield Hills Marian during Hughes’ freshman year, and then after defeating Marian in a District Final a year later, lost to West Bloomfield in a Regional Final.
When Hughes was a junior, the team got to the state’s final four, but a bad third quarter resulted in a heartbreaking one-point Semifinal loss to eventual champion Lansing Waverly.
A year later, when Hughes and other core players such as Brittane Russell, Timika Williams, Dhanmite’ Slappey and Briana Whitehead were seniors, they finished the job and won the Class A crown with a 48-36 win over Detroit Martin Luther King in the Final.
However, the signature moment of that title run actually came during the Semifinal round and was produced by Hughes, a playmaking wizard at point guard who made the team go.
Trailing by three points during the waning seconds of regulation against Grandville and Miss Basketball winner Allyssa DeHaan – a dominant 6-foot-8 center – Hughes drained a tying 3-pointer from the wing that was well beyond the 3-point line.
Lathrup went on to defeat Grandville in overtime and prevail against King.
Hughes said the year prior, she passed up on taking a potential winning or tying shot in the Semifinal loss against Waverly, and was reminded of that constantly by coaches and teammates. “I just remember in the huddle before that shot, that just kept ringing in my mind,” she said. “That was special. I cried for weeks not being able to get a shot off (the year before) and leaving the tournament like that.”
Growing up in Detroit, Hughes got into basketball mainly because she had five older brothers and an older sister who played the game. In particular, Hughes highlights older brother Gabriel for getting her into the game and taking her from playground to playground.
“I’m from Detroit,” she said. “We played ball all day long. Sunup to sundown. When the light comes on, you had to run your butt into the house.”
Hughes played for the Police Athletic League and also at the famed St. Cecilia gym in the summer, developing her game primarily against boys.
“My first team was on a boys team,” she said. “I was a captain on a boys team.”
The family moved into Lathrup’s district before she began high school.
Once she helped lead Lathrup to the 2005 championship, she went on to a fine career at UTEP, where she was the Conference USA Player of the Year twice and helped lead the Miners to their first NCAA Tournament appearance.
Hughes still holds school records for career assists (599), steals (277) and minutes played (3,777). On Monday, she was named to Conference USA’s 2024 Hall of Fame class.
After a brief professional career overseas was derailed by a shoulder injury, Hughes said getting into coaching was a natural fit.
“I had to make the hard decision, and I knew as a kid I wanted to be around basketball,” she said. “Once I made that decision (to quit), I knew I was going to coach.”
Hughes started coaching in the Detroit area, first serving as an assistant at Southfield A&T from 2016-20 and then at Birmingham Groves for a season. She then served as interim head coach at Colby Community College in Kansas before being named an assistant at UTEP in May 2023, a month after her former coach Keitha Adams returned to lead the program after six seasons at Wichita State.
While fully immersed in her job with UTEP, Hughes’ high school memories in Michigan certainly aren’t going away anytime soon – especially with the 20th anniversary of Lathrup’s championship coming up.
“We are still close friends because we all essentially grew up together,” she said. “They are still my friends to this day.”
