Father & Son Seidl Have Much to Discuss, Notes to Compare From Perfect Starts

Matt and Derek Seidl have a lot to talk about these days.
The father and son duo both have highly-ranked, undefeated basketball teams going into the first full week of February, something neither of them saw coming.
“We were hoping for a season like this, but you never think about winning this many in a row,” said Matt Seidl, the father and head coach of the 15-0 Olivet Eagles. “When our season ended last year, we knew our top seven players would all be returning.”
About 50 miles south of Olivet, in Jackson County, Derek Seidl has the Napoleon Pirates off to a 14-0 start. They are sitting on top of the Cascades Conference.
“We have a really talented group right now,” Derek said. “We were 19-3 last year and brought six guys back. Having that experience has been very valuable.”
Olivet is ranked No. 2 in MPR in Division 2 while Napoleon is No. 9 in Division 3. Both are top-10 teams in the latest Associated Press polls as well.
Matt Seidl, 60, graduated from Ypsilanti Lincoln High School in 1981 and went to Eastern Michigan University to become a sportswriter. He didn’t begin teaching until he was in his early 30s, but, by then, was already a veteran coach.
“It was getting difficult because I was always leaving my job to go coach,” he said. “I decided to go and get my teaching degree.”
He wound up in the classroom, which enabled him to dive deeper into coaching. He spent several years coaching at the middle school and high school levels, boys and girls, with stops at places like Pinckney, Ypsilanti, Manchester, Willow Run and Romulus. He was the JV boys basketball coach at Dexter when his son, Derek, made the team as a freshman.
By then, Derek already knew he would be on the bench one day as a coach.
“I played for my dad in youth travel stuff, and he was on staff for one year my freshmen year of high school,” Derek said. “He was a varsity coach all growing up. I was always at games. I loved talking to him about the game, the strategy of it, the Xs and Os. Even when I was younger, I thought about coaching someday. Growing up if you would have asked me what my dream job was, it would have been a teacher and coach.”
Derek, 27, graduated from Dexter in 2014. He played four years of college basketball at Lawrence Tech University. After getting his master’s degree and teaching degree, he got his first coaching job as an assistant coach at Chelsea, under Josh Tropea, who also had coached with Matt.
Derek’s first teaching and head coaching job came at Springport in 2019-20. This is his third year at Napoleon.
“It’s been a really good fit here,” Derek said. “Before I started looking into the job, I barely knew anything about Napoleon. It has worked out well.”
Matt is also the athletic director at Olivet. If he would have had his way, Derek would be coaching at Olivet.
“Derek did a really good job at Springport, and we had an opening and he interviewed and was recommended for the job, but before they offered it to him, Napoleon hired him,” Matt said. “He would have been the perfect choice to teach math and coach basketball.”
With Derek no longer in the running, Matt came out of coaching retirement and was named head coach.
“It was going to be a one-year deal, sort of a band-aid to get us to the next year,” he said.
Instead, Matt’s stayed on and put together quite a successful team. The Eagles have gone 47-6 since the start of the 2020-21 season. This year’s team has taken a big step.
Junior Bo Lincoln, a 5-foot-11 junior point guard, leads the team in scoring (17.1 points per game), assists (3.6 per game), steals (3.0 per game) and free throw percentage at 78 percent.
Drew Priddy, a 6-5 senior center, is averaging about eight points and seven rebounds a game, and junior guard Bryce Wine is averaging nine points a game and leads the team in 3-pointers.
“We had quite the youth movement a few years ago,” Matt said. “We go 8-9 deep now and have a lot of experience. Having those young guys play a couple years ago is paying off.
“We are a good team, but we’re not a 70-possessions-a-game type of team. We know who we are.”
Derek also knows plenty about his dad’s team.
“I definitely keep track of them,” he said. “We talk on the phone on a daily basis – 30 minutes about Napoleon and 30 minutes about Olivet. We bounce things off each other. We run a lot of the same stuff as far as systems. We’re very connected on things.”
Matt and Derek’s teams tried to have a good old-fashioned scrimmage, or exhibition, last year but – with Derek’s team ahead – Matt received two technicals and got kicked out of the game. It’s a fun story for both to tell now.
“That was wild,” Derek said. “It was a cool thing we had going. We were winning so I was enjoying it, but that put a whole different spin on the situation.”
Matt said they probably won’t do that again. Probably.
“My wife said no,” he said. “Derek and I have talked about it, but I don’t know that it would ever happen.”
Derek said one day he’d like to coach with his father.
“I’m very energetic and into it, just like he is,” Derek said. “There are some similarities. I played for him and watched him a lot. I try and pull some of the things he does, being prepared. We get along super well. I don’t know if I could trust him to not get technical fouls.”
He’s kidding, of course.
Napoleon has a core group of four players with a ton of experience.
Devonta Habern is a 5-11 junior who is on the varsity for the third year and runs the show at point guard. Six-foot-5 senior Trent Jester is one of the best big men in the conference. University of Michigan baseball commit Grant Bradley is a three-year varsity starter and outstanding athlete. Holden Vanpoppel is an all-state track athlete who has turned into a pretty good basketball player.
“Grant is super steady and having a great year,” Derek said. “He looks like he’s been in the weight room since he was 5 years old. He can guard anybody. Vanpoppel is an unbelievable run and jump athlete. All four of these guys are averaging in double figures. They are really good athletes who have invested in the program and put the time in.”
“We’ve got a very talented group,” Derek said. “They are a little looser than I am. I tend to be very calculated, kind of analytical and serious. They like to goof around a little bit. They keep me even-keeled. They know when to get serious. It’s good for me to have a group like that.”
Derek said his squad wants to exceed expectations this year.
“We talk about that after every game – don’t be satisfied just because we are undefeated,” Derek said. “There is plenty more to accomplish. Last year we went 18-2 in the regular season and 19-3 overall, but we didn’t win a league or a District. Our guys have bought into that mindset. That’s helped us get to where we are.”
Matt is keeping a close eye on not only his team, but Derek’s as well.
“I probably get more stressed watching his games,” he said. “I’m really proud of what he has been able to do.”

Niles' Arnold Remembered as Teacher & Leader, 'Doing Exactly What He was Meant To Do'

NILES – Throughout his 22-year career coaching varsity girls basketball at Niles High School, Jim Arnold required one thing from his players.
Just have fun.
"Jim always stressed to his players that the one thing he wanted them to do when on the floor was to just have fun playing the game," said George Brawley, who served 15 seasons as one of Arnold's assistant coaches at various levels.
Arnold, 81, died Dec. 9 following an extended illness.
But throughout his career, Arnold's teams did much more than just enjoy themselves. The Benton Harbor native built a highly-successful program at Niles, where he achieved an overall win-loss record of 360-139 from 1986-2008, with 19 winning seasons. Under Arnold's watch, the Vikings captured seven conference titles, 10 District championships – including nine straight from 1997-2005 – and five Regional crowns.
Among Arnold's other accomplishments were being named Class B Coach of The Year by The Associated Press in 1998 and receiving honorable mention in 1997, along with selection by the Basketball Coaches Association of Michigan as Region 5 Coach of the Year in 2002 and 2004. He was also named conference Coach of the Year seven times and received the Herb Quade Memorial Sportsmanship Award for the 2002-2003 season.
Arnold also coached Niles to back-to-back District championships in softball in 1993 and 1994.
As young athlete himself, Arnold excelled on the baseball diamond. A successful player while at Benton Harbor, he also played on Twin City American Legion teams and was known as a team captain and a coach on the field. Arnold later had an invitation to try out at the professional level with the Baltimore Orioles, but an injury ended his pursuit of that dream.
Arnold later played third base for Bargain Center, a slow-pitch softball team that won a regional championship and went on to play in the national title game in St. Louis, Mo.
His daughters Sonya and Allison were among the athletes that Arnold mentored during his coaching career. Sonya (Martinez), his oldest daughter, played for her father in eighth grade.
"He made the game fun, and you wanted to do your best because you didn't want to disappoint him. He poured his heart into each and every practice and game because preparation mattered to him. He demanded excellence, and every player became better because of his coaching ability," said Martinez, a 1986 Niles graduate.
Allison (Clay) his youngest daughter, played on the 1990 Niles varsity squad that finished 25-1, winning conference, District and Regional titles. She is a 1991 graduate.
"It was awesome playing for my dad. Some of my best memories in my life were during that time,” Clay said. “He had high standards and inspired others to be the best version of themselves. He put his heart and soul into what he did, and I had a front-row seat to that."
Linda Arnold has fond memories as a coach's wife.
"I loved watching my husband coach because of the joy it brought him. His passion, intensity and the love he had for his players was genuine,” she said. “It was more than a game. It was more about developing players in the area of discipline, teamwork and giving your all. Even in the busiest part of the season, he always made me feel like a priority. I didn't just watch a coach. I watched a man doing exactly what he was meant to do.
"My husband coached with passion, but he loved his family with intention. My girls would go to his practices and we all attended his games, and we had the team over for team dinners. His players were a part of our extended family. He made sure we felt a part. He was the best coach in the world, and he was mine."
Jim Arnold was highly respected by his coaching peers. He was kind and treated everyone with dignity. The community of Niles knew what he stood for and they knew his standards were high. He was admired for his preparation and understanding of the game as well as his commitment to doing things the right way. He was strict but fair and treated everyone the same, whether you were the star player or last one off the bench, Martinez explained.
"Developing his players' character was far more important to him than winning," she said. "Dad lived what he taught. He modeled humility, hard work and lived a life of integrity. He made people better by being a part of their lives."
When Jim Arnold first began his junior high teaching career in Niles, he also coached the boys junior high basketball team. There were no girls basketball teams at the time, so a girl tried out for the boys team. She was good enough to make the team, so Arnold kept her. The following school year, the principal asked Arnold to organize a girls team – and the rest was history.
Former Niles varsity girls basketball coach Jessica Johnson, a teammate of Clay’s, recalls the experience of playing for Coach Arnold.
"Coach Arnold taught us discipline, resilience and always required 110 percent effort from you. He would instill confidence in you while still holding you accountable," said Johnson, now an assistant women’s basketball coach at Southwestern Michigan College.
Johnson recalls Arnold's use of comic strips as a teaching tool to help his players improve upon their mistakes.
"If you had a game where you didn't shoot very well or took questionable shots, he would place pictures of bricks in the gym the day following the game," Johnson said.
"Coach Arnold went out of his way to build that relationship and trust with his players. He gave us lessons that extended way beyond the court that made us better people."
Mark Haase, a Niles alumnus and the current Vikings head varsity boys basketball coach, also had the privilege of playing for Arnold.
"I played freshman basketball for Coach Arnold. It was one of the most disciplined and well-conditioned teams I ever played on. He ran a tight ship, but it was done out of love and concern for his players. He has a great family and is a Niles legend," Haase said.
Niles athletic director Matt Brawley referred to Arnold as an amazing teacher, coach and individual in the school and community.
"Coach Arnold would never ask you to do anything he wouldn't do. He was very structured and expected a lot out of his players, and he got results without excuses,” Brawley said. “He was a true leader of Niles athletics. He was an unbelievably kind and humble individual.”
