McCullen Reaches 500-Win Milestone Leading DeWitt's Girls 'Basketball Family'

February 17, 2023

Bill McCullen is in the midst of his 27th season coaching at DeWitt, taking the helm of a girls basketball program in 1996 that had struggled with a 28-37 record (14-22 in league play) over its three previous seasons. 

Mid-MichiganReaching 500 wins is an incredible achievement, as only 14 other girls basketball coaches have done so in the state of Michigan. He led the Panthers to that 500th win Thursday against East Lansing, and after the 61-40 victory he sits sixth among active coaches on the MHSAA girls basketball coaching wins list.

The Panthers currently sit 17-2. McCullen has posted a 242-38 league record (.864 winning percentage) with 19 league championships as DeWitt eyes a rematch with Capital Area Activities Conference Blue leader Holt coming up Tuesday. The Panthers also have won nine District and five Regional championships and reached the MHSAA Semifinals four times and finished Class A runner-up in 2014-15.

Before COVID-19, he had averaged 19 wins per season (to just 3.96 losses) in a sport that had a 20-game regular season before this winter. McCullen reached his 100th win in just five seasons, averaging an incredible 20 wins over that early span. DeWitt has posted 10 20-win seasons in the program’s history; McCullen is responsible for nine of them.

The expectations of McCullen’s student-athletes are just as high in the classroom. During his first 26 seasons, the Panthers have averaged a team GPA of 3.52, earning the state’s top honor three times. McCullen has seen 28 of his student-athletes earn academic all-state recognition.

McCullen has dedicated 30 years as an educator, teaching social studies classes at DeWitt High School for the last 29. Above all the wins, McCullen is an exemplary role model for coaches, players, and parents. His behavior on the sidelines and how he talks to officials and players exemplifies what is expected of coaches.

He has taken teaching and coaching beyond the classroom and hardwood and has created a “basketball family” within his program. McCullen is quick to give credit to his assistant coaches (Sam Dalman, Annie Jenkins, and Marcy Uyl) and longtime friend Scott Palmer, who served as his varsity assistant for two years and JV head coach for another 24. The support of his wife (Denise) and two grown sons (Carter and Jerod) are paramount to McCullen’s success and passion for teaching and coaching. 

Perhaps his greatest influence was Jim Lutzke. Then DeWitt’s director of human resources and athletic director, Lutzke hired McCullen in 1994 as a teacher and to coach tennis. Lutzke mentored McCullen for five years before succumbing to cancer in 1999. That relationship has had a profound and lasting impact on McCullen as a husband, father, teacher, and coach.

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.

Bay & ThumbAs 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 elevates for a shot while defended by a pair of Panthers. 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.”
