McCullen Reaches Milestone: 300 wins

March 7, 2012

Bill McCullen truly earned his 300th coaching victory — the program’s first-ever tournament win as a Class A school — in the first round of MHSAA District action by defeating No. 4-ranked St. Johns on Feb. 27.

After the Redwings hit two free throws, McCullen called a timeout with 9.9 seconds left, down one, and the length of the floor to go. He drew up a play that was introduced to his team only the day before — senior Kalya Hanses to inbound the ball to senior Erica Goodenough, who was to get the ball to sophomore Lexi Banaszak at the division line. Banaszak was instructed to get the ball to left-handed freshmen Claudia Reid on the left wing, giving her a 2-on-1 break with junior Kaylee Schmit. 

McCullen finished drawing up the play in the team huddle by saying, “We are going to score, and this place is going to go crazy!”

The play worked as it was drawn up. Reid received the ball and saw an opening to the basket, hitting the layup with 3.3 seconds left. McCullen was exactly right; the score went in, DeWitt won 36-35, and the home crowd did go crazy.

McCullen just completed his 16th season coaching the Panthers, 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.

The 300-win milestone is an achievement in itself — but more amazing with a closer look.

Under McCullen’s leadership, the program has posted a 150-20 league record (.882 winning percentage) while winning 13 league championships (including seven straight through this season), seven District championships, three Regional championships, and three MHSAA Semifinals appearances. 

In a sport with a 20-game regular season, he has averaged 18.75 wins per (to just 4.25 losses). McCullen reached his 100th win in just five seasons, averaging an incredible 20 wins over that span. DeWitt has posted six 20-win seasons in the program’s history; McCullen is responsible for five of them.

In the history of MHSAA girls basketball, McCullen is the 44th coach to reach the 300-win plateau and only the sixth from the Lansing area. His win total and .815 winning percentage places him eighth and second, respectively, among active coaches.

Expectations are just as high in the classroom. McCullen’s squads have averaged a team grade-point average of 3.59 (with a 3.84 team GPA this season), earning top honors in Class B twice during the 2000 and 2010-2011 seasons. Nine players have earned academic all-state honors.

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, building an uncanny rapport with what he calls “my girls.” 

McCullen would likely recognize his wife (Denise) and two sons (Carter and Jerod) for their support and countless sacrifices, and he would also quickly shift credit for his success to the many assistant coaches throughout his tenure. His mentor, Jim Lutzke (who coached at DeWitt for six seasons before succumbing to cancer in 1999), had a lasting and profound impact on McCullen; Luztke undoubtedly would be proud.

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.

Southwest CorridorThe 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.

Junior point guard Brayden Carpenter (0) returns for his second varsity season at Three Rivers."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.

Senior Braylee Burg (52) returns for her second varsity season for Three Rivers.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.
