Putting her name atop the single-season scoring list at Port Huron High was a proud moment for Mariah Turner.
But it took a note from her father to realize the magnitude of breaking a record that had stood for 29 years.
“I didn’t really think about that, but my dad texted me before he went to sleep one night, and he was saying how proud he was of me, and how great it is to do something like that that had lasted over so many years,” Turner said. “That kind of made me think more of it, that it is more important.”
Turner finished the regular season with 442 points, averaging just over 20 points per game. Her total passed Kesha Bradford, who scored 429 points during the 1997 season before going to play at Valparaiso and Purdue-Fort Wayne.
A 3-point shot in the regular-season finale against Croswell-Lexington, a 63-39 win for the Red Hawks, gave Turner the record.
“As soon as I shot the 3, Coach called a timeout and we celebrated as a team,” Turner said. “It felt really great and relieving. It made me realize how much work I put in, both in-season and the offseason, to make history.”
During her senior season, Turner has led Port Huron to a 14-9 record and a spot in the Division 1 District Finals. The Red Hawks will play New Baltimore Anchor Bay tonight at Macomb Dakota.
As this season progressed, breaking a 30-year-old record wasn’t on her mind.
“It was later into the season, my coach (Jermaine Drake), he must have had his eye on it,” she said. “Because he was telling me, ‘You need 70 more points to beat the school record,’ or whatever. But I couldn’t let it affect me. I had to let it come to me and play my normal game.”
Turner’s normal game is being a do-everything guard for the Red Hawks. Not only did she set the school record for points this season, but also had a record 82 steals during the regular season. She had an eight-steal game, as well, which is tied for best in school history.
“She’s our best defender, our best scorer, third in assists, first in steals, first in 3s, top three in rebounds – she kind of just does everything for us,” Drake said. “She has a motor and never gets tired. She’s kind of like the whole engine of the team.”
Drake, who is in his first year as varsity coach, moved Turner off the ball to the wing this season – as she had shared point guard duties before – opening up the Port Huron offense.
But much of the Red Hawks’ offense is created through its defense, and the transition game is where Turner really shines.
“We press a lot, and she plays the passing lanes and kind of double teams if she’s able to,” Drake said. “Even off defensive rebounds, she’ll read it and leak out and get up the court. I try to implement us getting out as quick as possible to not let the defense set up.”
Turner’s combination of speed and smarts fits perfectly into what Drake wants to do. She’s one of the Red Hawks’ top performers on the track, an all-Macomb Area Conference performer in the 100- and 300-meter hurdles.
She’s also a 4.0 student and four-year varsity player.
“She leads by example every single time she’s on the court,” Drake said. “I don’t think she’s lost a sprint in conditioning this year. She hasn’t missed a practice. She’s like the perfect player you can ask for as a coach – no attitude, doesn’t complain.”
Turner plans to continue playing after high school. Basketball will likely be the deciding factor for the school she attends, as she wants to be a flight attendant, which will require training after she’s done with college.
“I like to travel a lot,” she said. “I went on a plane in like eighth grade for the first time, and I was watching the flight attendant the whole time. They help people, and they get to travel.”
Before she takes off, there’s still business to finish during what's been a rewarding season for Turner and the Red Hawks.
“We had some ups and downs and we had to figure each other out as a team, because we had a lot of people from JV come up this year, and we’re younger,” she said. “It was hard to adjust, but we just had to work on it and take practice seriously to bond more and learn how each player plays.”

Soccer, Hoops Next to Seed Using MPR
August 6, 2019

MHSAA benchmarks editor
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.
