The greatest girls basketball season in Carleton Airport’s history hasn’t come without its adversity. When it hit, however, it only made the Jets stronger.
Tonight, Airport (24-2) – which already has set a school record for victories, broke the single-game Monroe County scoring record and won the first Regional championship in school history – will play a Quarterfinal against reigning Division 2 champion Tecumseh.
The journey to get here has been magical, said head coach Darrell Mossburg.
“Something just clicked with this group,” he said. “Their focus has been so much better. They watch film, they pay attention to scouting reports. They’ve learned you have to play every single possession and not worry about a missed shot or turnover. It’s next possession, next possession.”
The Jets have four seniors, all who have played several seasons on the varsity. Olivia Gratz is a 1,000-point scorer, but not the leading scorer on the team. That distinction belongs to junior Sophia Mator, who averages 17 points a game and has made 60 3-pointers on the season.
Senior Peyton Zajac is right behind them in scoring and has been a big contributor in a variety of ways.
“Peyton hasn’t been a great scorer, but there are other things she does that people don’t see on the stat sheet, getting our people in the right spot and playing defense,” Mossburg said.
Senior Jillian Baker has made perhaps the biggest strides since last season.
“Jillian has been playing extremely well. She’s scoring more,” Mossburg said. “Brooklyn Martin (sophomore) has been playing great. They provide the depth that you need this late in the year.”
Seven Jets have scored at least 100 points on the season. Airport averages a whopping 67.6 points per game, and put up a 103-point outburst against Huron League foe Milan in the first game in February. Airport has scored at least 70 points 12 times.
“The defense can’t key on just Sophia,” Mossburg said. “We have a lot of depth.”
Mossburg said this is one of those years that Jets faithful have been talking about for many.
“I know the program all the way down to the fourth grade,” he said. “We knew when this group were seniors, when we could mix in a couple of the other players, we knew they were going to be really, really good.”
In years past, he said, his players didn’t always have the same approach to practice. Now, everyone is on the same page.
“You have to practice like a winner, and every day you have to practice like a winner,” Mossburg said. “They finally grasp that concept. They’ve realized this is it. We have to come to practice every day and act like a winner.”
The team’s basketball IQ is off the charts, he noted.
Sophomore Mya Stahr’s dad and uncle were basketball stars at Flat Rock. Junior Katelyn Roecker is the daughter of a former head coach and basketball official. Freshman Brityn Duffy’s dad was Airport’s football coach and played baseball at Michigan State University.
Jillian Baker is the daughter of Luke Baker, who coached the Jets for much of the season when Mossburg had to step away for health reasons. Baker’s niece, Brenna, is a senior on the team as well.
“A lot of good basketball families,” Mossburg said. “They have the right basketball IQ and have been brought up the right way,”
Baker has been an assistant with Mossburg for five seasons and was the natural choice to step in when necessary.
“Luke has been fabulous,” Mossburg said. “He has been great. He does what’s right for the program. He puts his time in with film and scouting reports. Without him, I don’t know where we’d be.”
Mossburg has been around sports his entire life, graduating from Airport in 1988 and playing football at the University of Toledo including under coach Nick Saban. Mossburg’s dad was a longtime coach in Monroe County who had a fling in professional football.
Mossburg stepped away for the early part of the season but returned to the bench in February in an assistant coach-type of role. Even when he was in the hospital, he and Baker communicated daily. It was agreed that when the postseason began, Mossburg would be back as the head coach.
“I always told the kids that the coaches aren’t between the lines playing,” Mossburg said. “It’s been a smooth transition. No worries at all.”
Mossburg said he’s weathered the storm with his health. The focus now is on playing a Tecumseh team seeking to repeat as champion.
“We have to focus on us and not play to the scoreboard,” he said, “keep our focus on possession by possession, one shot at a time, one rebound at a time.”

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.
