Genesee's Zinn Setting School, Family Records While Climbing MHSAA All-Time Lists

Averie Zinn had a front-row seat as her sister Ryleigh re-wrote the Genesee girls basketball record book.
As a middle school student, and then freshman teammate whose parents are the Genesee coaches, Averie saw exactly what it took for Ryleigh to get there.
She also had a pretty good idea of what would be required to overtake her.
“I remember when I was little I was like, ‘Yep, I’m breaking all her records,’” Averie said. “My mom’s sister, she held all of those before. But I just remember when Ryleigh was getting those records, I was like, ‘Well, I’m going to break them.’”
Averie Zinn has broken those records and then some, splashing her name across the MHSAA record book with most of her senior season still to go.
She’s scored a school-record 1,892 points during her career, and with a per-game average this season of 39.8, could surpass 2,000 by the end of next week – making her the 34th girls basketball player in state history to eclipse it.
If that average holds throughout the season, and even if the Wolves play the minimum number of games remaining, Zinn could become just the seventh female in the state to hit 2,500 points.
That, of course, is a projection of where she could be, but she already appears 20 times in the MHSAA record book.
Her 851 points scored a year ago are third highest in a single MHSAA season. Seven of her single-game scoring performances are listed, including five games of 50 or more (she’s added another 53-point performance already this season that is not yet listed).
Her 21 points in a single quarter are tied for third all-time – she’s since hit 22, which will tie her for second.
She made 186 free throws a year ago, 10th-most in a single season, and has three games of 15 or more makes from the free-throw line.
Then there’s the steals: Two seasons in the top 12 all-time with 218 a year ago (third) and 170 as a sophomore (tied for 12th), and five games with 15-plus.
“I just think it’s such a blessing,” Zinn said. “No one really gets that opportunity, it’s such a select few amount of people. I almost don’t even think I’ve processed it. I think it’s really cool, and the fact that it’s happening with my parents coaching me, it’s really cool.”
Zinn, a 5-foot-10 point guard who also takes the opening tip for the Wolves, has scored 199 points through five games this season, going over 30 in four games and over 40 in two of those four.
She’s recorded 48 steals, as well, going for double digits (11, 12, 16) in each of her first three games.
“I mean, she’s 100-percent locked in,” said Genesee coach, and Zinn’s dad, Mike Zinn. “She’s been training hard with strength and conditioning, working on her range – a different range. Normally, she shoots from pretty deep, from nearly halfcourt like it’s nothing. But she’s been wanting to work on her mid-range game a little bit.”
As the Zinns have had their successes, so has the Genesee program. This year’s team is off to a 4-1 start, and last year the Wolves won a District title and advanced to a Regional Final in Division 3 for the second time in program history. The first came during the 2022 postseason.
Both of those seasons resulted in 17 wins, which is a school record.
The District title in 2022 was the program’s first since the mid-1990s, when their mom, Megan was playing.
“Mike and I graduated from Genesee High School, and we were the last ones to win a District title,” Megan Zinn said. “We decided to stay in the community, raise our kids in the community and coach here. It’s bigger than basketball. We believe we could work to put Genesee on the map, and that’s exactly what we’ve done. Last year, going to the Sweet 16 was the furthest we’ve ever gone. We lost both times, but just to say that we could get there while coaching both of our daughters is pretty special.”
When Averie Zinn is done breaking records at Genesee, she will continue her basketball career at Wayne State University.
She committed this past summer to play for the Warriors, a program she’s felt connected to for years. Not only is assistant coach Andy Ayrault a family friend, but Zinn caught the eye of head coach Carrie Lohr while hitting deep 3-pointers as an eighth grader at a team camp.
“I’m really excited,” Zinn said. “I’m getting more and more excited, especially since the new year is here and knowing this is the year that I’m going away and playing there. I know a lot of my teammates already. Wayne State feels like another home to me. That’s what was most important in my decision.”
Genesee won’t be without Zinns, either. While Mike and Megan will continue coaching, there’s also another player coming through, as Averie and Ryleigh's younger sister Maylee Zinn will be a freshman next season.
“I’d say the (age) gap for me and Maylee is like one year too far,” Averie said. “Me and Ryleigh played together, we would go to trainings together. We got super close that year (they were teammates). I always say that to my mom, that I wish I was back a year so I could get that year with Maylee. She’s pretty good.”

Past Wildcats Bringing Valuable Experiences Home as Three Rivers' New Hoops Coaches

THREE RIVERS – Basketball has always been a passion for rookie Three Rivers coaches Drew Bosma and Michael Morrison.
The two former Wildcats aim to bring that same level of energy they exhibited during their playing careers as they embark on their first varsity coaching stints.
Both Bosma and Morrison have brought along a few familiar faces as they begin working to rebuild Three Rivers' strong basketball tradition.
Bosma, a 2009 graduate, replaced long-time mentor Brian Burg as the Wildcats' varsity boys coach, while Morrison has taken the reins of the girls program from Carley Shoesmith.
As a student-athlete at Three Rivers, Bosma excelled in football, basketball, baseball and track & field. He continued his playing career at Alma College and Liberty University before returning home and completing his undergraduate studies in psychology through online courses.
"My psychology background has been useful in my coaching career. The kids you work with have so many different issues they encounter than when I was in school," said Bosma, who is employed in the RV Industry at Grand Design in Elkhart, Ind.
Bosma's early shift works out perfectly with his coaching duties. After 11 seasons as Three Rivers’ JV boys coach, he spent the last two as a varsity assistant at Portage Northern. His immediate goal is to renew enthusiasm within the program.
"My experience with Three Rivers basketball as a player was a very good one. I want to build the culture to the point where people want to be here, the effort isn't questioned and (we) have kids who enjoy the game," Bosma said. "I've had a lot of good mentors in this game. Now that I'm a head coach, I want our players to be able to step onto the court and play freely. Yelling after every mistake they make isn't going to teach them anything. They are going to make mistakes in life, and they have to understand it’s ok to mess up and learn from those mistakes.”
Bosma's additional goals this season are simple ones.
"I want our kids to make it known that we have competed hard in every game with a no-quit attitude. It's a coach’s dream to win every game, but I want to make sure these kids are becoming better people as well as basketball players," Bosma said.
Long-range goals include increasing interest among students to try out for the team. He and his staff have organized the Three Rivers NextGen Boys' Basketball Program for students in kindergarten through eighth grade that will begin in January and focus on building skills and nurturing players who may fill the ranks down the road.
Bosma's coaching philosophy includes being tough on his players while showing that he truly cares about their well-being.
"As a coach I'm going to be hard on you, but these guys know that it’s out of love and concern for them,” he said. “They understand that anything I say to them is meant truthfully, and it comes from the heart. I want them to know they can come and talk to me. I want them to return 10-12 years later and notice the same type of feeling in this program. All of my coaches are either former teammates of mine or guys who played for me.”
Tirrell Hausmanis, a former hoops star at Three Rivers, serves as Bosma's varsity assistant. Brenden Brown is the Wildcats' junior varsity mentor, and alumnus Thomas O'Dell is the freshman coach.
"Having Three Rivers alumni on our coaching staff teaches these kids how important basketball is to our community," Bosma said.
Offensively, Bosma expects the Wildcats to be able to stay in space and use their long wing players and better shooters to their advantage. Among the top returners are junior point guard Brayden Carpenter, 6-foot-6 senior forward Zander Barth (who is committed to Central Michigan for football), and senior forward Carter Langston.
Carpenter averaged 13 points per game as a sophomore, as Three Rivers finished 7-15.
"You can tell there's a different attitude under the new coaching staff. There are lot of guys now who want to put in the extra time and energy to get better,” Carpenter said. “Our communication on the court has improved, and Coach Bosma's system allows us to play freely without worrying about the consequences of making a mistake.”
Three Rivers looks to be more adaptable at the defensive end.
"Defensively I want to change things up all the time. We don't want to just sit back in one zone or play man-to-man, but rather press whenever we can,” Bosma said. “We have a group that has improved its basketball IQ, which allows us to do so much more as coaches. We have good team camaraderie and kids who are going to play for each other. These guys are more excited about getting the win rather than what shows up in the box score.”
Bosma has seven seniors on his roster, but Three Rivers still is a fairly young team in terms of experience.
"We have long and athletic kids and guys who could be pretty good once they build their confidence level. We have great guards and kids who like to defend. Defense has become somewhat of a lost art in high school basketball. We have the tools though to be a successful basketball team," Bosma said.
Morrison, a 2003 Three Rivers graduate who played football, basketball and baseball for the Wildcats, has taken the reins of the girls program. After high school, Morrison attended Ferris State University where he graduated with a psychology degree as well. He is employed as a probation officer for the state.
Morrison has extensive experience coaching basketball. He started out coaching travel basketball in Paw Paw while also coaching high school teams at Kalamazoo Loy Norrix, Vicksburg and Three Rivers, including the last five years as the JV boys coach under Burg. He also served as an assistant men's coach at Glen Oaks Community College under Mike Elliott.
"Working under Mike taught me so much more about basketball and has made me an even better coach. That time was very beneficial," Morrison said.
Morrison's immediate goal is to provide stability in the girls program.
"These girls have had several coaches in the last few years. I want to provide some stability and help the program grow from the lower levels,” he said. “Obviously you want to win championships, but right now we have to start with attainable goals like finishing over .500, which we haven't done in a while.”
Other goals that Morrison feels are within Three Rivers’ grasp are finishing in the top half of the Wolverine Conference and competing for a District title. The Wildcats were 8-14 last season and tied for sixth in the league.
His philosophy centers around pace and space.
"I want to get up and down the floor and defend. We want to execute an offense in the halfcourt, but also get up and down the floor and get some fastbreaks when we can. We spent the first couple weeks of practice working on executing things the right way," Morrison said.
Senior guard Dani Glass, a second-team all-Wolverine Conference pick last season, returns for her fourth varsity season. Glass, who averaged 12 points per game as a junior, has committed to play at Kalamazoo Valley Community College.
"Dani makes us go and is our catalyst for everything we do offensively. We expect more from her this season as she gets ready for the next level," Morrison said.
Sophomore post player Braylee Burg will be another key component for the Wildcats, along with senior defensive specialist Jersey Roehrs.
"I feel I help my team most with my ability to box out and create a lane for my guards along with providing rebounding. I want to work on finishing stronger at the rim this year,” Burg said. “Our coaching staff has us doing fun drills that are getting us ready for the season. We want to get the ball down the floor more effectively and set up our offense."
Morrison is most excited about his team's work ethic.
"We are very excited about this team's potential and are really leaning heavily on our seniors to give us a big great burst of energy and bring everyone else along,” Morrison said. “People are going to see a very well-disciplined group that works hard and together as a team. We are working extremely hard on our communication and shooting as well."
Parker Ellifritz, who ranks among Three Rivers’ all-time leading scorers, serves as Morrison's varsity assistant. Olivia Hancock, whose played on the 2016 Class B championship team at Marshall during her prep days, fills the role of junior varsity coach with Payge Ellifritz, Parker's sister, serving as her assistant.
