Dock Putting Dad's Coaching Lessons to Work as Middleville TK Continues Climb

MIDDLEVILLE – Denny Dock can't pinpoint the exact moment he thought his football-loving son would follow him into coaching, but the signs were there all along.
For starters, there were the countless hours spent tossing a football around the backyard. Or when his young son, Jeff – not even old enough for middle school at the time – eagerly joined other Stevensville Lakeshore coaches watching film on weekends.
Maybe it was all those Friday nights spent trekking along the sideline as a ball boy for Lancers teams. Another clue might have been the Saturday afternoons the two spent together watching college football, or taking in the NFL on Sundays.
When Jeff got older, it may have been how he readily absorbed tips that helped him become a better quarterback in high school and then at Grand Valley State. It could have even been an early, uncanny ability to grasp the importance of fundamentals.
Put it all together, and it seemed inevitable coaching football loomed in Jeff Dock's future.
"That's very fair to say," said Denny Dock, who is 19th on the state's list of all-time winningest football coaches while also the winningest high school softball coach in the country. "The younger years in football were really positive for Jeff, and that doesn't happen all the time. There are negative things that can happen."
While there might have been multiple signs the younger Dock would one day join the coaching ranks, he admits it was far from a done deal. There were thoughts of becoming a biology teacher, a pastor or maybe even an orthopedic surgeon.
But coaching? Even with his father as a classic example of the positive impact a good coach could spread, Dock said it took years for him to eventually land in coaching.
"It dawned on me that there were a lot of all three of those things in being a coach," he said. "Growing up in sports is what I knew, and I ended up developing a passion for it."
That passion is actually the highest it's been in years as his Middleville Thornapple Kellogg football team this past weekend improved to 7-3, continuing the program's first winning season since 2020 and the best fall since the Trojans went 7-3 in 2018. The Trojans defeated Hastings 28-20 in a Division 2 playoff opener, and a win this Friday at Lowell would give Middleville its first District championship since 2001.
Denny Dock coached football at Hartford from 1981-83, Dowagiac from 1984-87, and then Lakeshore from 1988-2013, returning to lead the Lancers for one more season in 2020 and all together totaling a 270-79 career record, 15 league titles and five runner-up MHSAA Finals finishes.
He has kept his hand in football in aiding his son's Trojans program. He's at all the games to add support, critique, advice, strategy, tips on how practices can best be organized and long talks discussing how continual improvement can be furthered.
It's a two-way street as an old football coach who never had a losing season, and is a member of the Michigan High School Football Coaches Association Hall of Fame, can remain invested in the game while his son benefits from three decades worth of experience.
Jeff Dock said his father's real value is his ability to spot from the stands the little things that less experienced coaches may miss.
"Play calling, how players are used, maybe a little bit about strategy," Dock said.
After playing for his father, Dock said there's no doubt he's transferred the best of what he learned into his own coaching. The older Dock was not only a highly successful football coach, he's compiled a 1,319-345-2 record in softball with eight Finals titles.
Whether it's about football or the philosophy Dock stresses in his softball program, the advice accepted from his father – who still attends softball clinics for tips on improving the Lakeshore program – is virtually across the board. It begins, however, with how a coach should treat his players.
"I was a manager growing up, and I saw his intensity and a love of his players," Dock said. "He never pushed me in any direction, but he told me about education. He always let me figure it out. One of the coolest things my parents did in raising me was to allow me to figure things out."
As far as the Xs and Os of coaching, Dock said his father prizes an organized practice. In fact, it could even be argued that both Docks enjoy a spirited and productive practice session over the microscope of Friday Night Lights.
"He never had a losing season, and it was ingrained in us just to go back to work and that that work never stops," he said. "He loves practices and being organized. Rule No. 1 with him was to make sure the players are prepared, and that you have to communicate with them. Dad would never belittle us or cuss us out.
"I saw the work he put in, how he'd wake up every Saturday thinking about the game. I saw the nitty gritty of coaching and how it was going to take work."
It was that seemingly endless work, in fact, that Denny Dock made sure his young son understood. Denny had no illusions over the pitfalls of coaching, and the pros and the cons. But before he could teach that to his son the coach, he made sure his son the quarterback understood how athletics worked.
There were challenges as a player and now for his son as a coach.
"He was always a quarterback because I think he liked the ball in his hands," Denny Dock said. "I think he liked the leadership part of the game, understanding the team part, and knowing what he had to do. That always challenged him."
While the challenge of playing is long gone for the younger Dock, the next challenge is building a program which is annually competitive. To do that, Jeff Dock said he accepts what his father knew 30 years ago.
"I'm willing to learn anything from anyone at any time," he said. "I know my dad has always thought about what he can do to become a little better every year. I'm always looking for ways to communicate and do things better. It can always be done better, but how can you get there? How can we do the little things better. That's what I learned."

Onekama Celebrates New Stadium, Legends Past with Eyes on Another Playoff Run

Pretty much every player who has put on the Portagers football jersey over more than six decades of Onekama High School football knows the name Jim Taylor.
And if they didn’t know it before the team’s 52-8 win over Holton on Oct. 10, they do now.
The community of Onekama honored their former coach, celebrated the 50th anniversary of the only undefeated squad in the Portagers’ history and dedicated the district’s new football stadium during the win over Holton – which also helped keep Onekama’s playoff hopes alive this fall.
The Portagers enter this weekend’s regular-season finale at Merrill ranked No. 14 on the 8-Player Division 2 playoff-points list. The top 16 qualify for the postseason, which begins next week.
“We love our history and traditions – all of the generations have just supported each other and built it into what it is today,” said fourth-year coach Justin Sedelmaier. “The former coaches are still involved, mentoring me. … Coach Jim Hunter and Coach Jim Taylor … still coming and seeing and saying hi to the team and stuff every now and then. The ’76 team, a lot of them like Jerry Brown, are always around supporting us.”
Brown, the quarterback of the only Onekama team to finish undefeated, was the primary organizer of the reunion. He was on hand for the celebration, along with Hunter and Taylor, and was even more excited about honoring Taylor than he was about the reunion.
“The motivation behind it for me anyway, personally, was to throw as much light on our coaching staff, and most specifically, the head coach, Coach Taylor, who had such a huge impact on so many lives – mine for sure,” Brown said. “This was all about shining a light on Coach Taylor and his wife, Lora – what a team. She's been right there with him all the way, supporting him.”
Lora Tayler was the school’s cheerleading coach during the first decade of football at Onekama. She was also on hand for the Oct. 10 festivities.
Brown was one of 14 players in attendance to honor the 1976 team, which finished 8-0 and won the Northwest Conference title but did not qualify for the MHSAA Playoffs, which were in only their second year and included only four teams statewide per Class at that time. (Other Onekama teams have since finished perfect for the regular season but lost in the playoffs.)
Taylor started the football program in 1964 and served as head coach until 1988. During his time guiding Onekama, Taylor compiled a 124–58–3 record with only two losing seasons over 22 years. He returned to coaching as an assistant at Onekama from 1997-2008 and was inducted into the Michigan High School Coaches Association Hall of Fame in 2005.
During Taylor’s early years, the Portagers played their home games at nearby Manistee High School while waiting for a home field of their own. The new stadium was built thanks to support of a successful 2024 bond proposal which also provided enhanced security technology, an updated gym, new playground equipment, pickleball courts, team rooms and a modernized press box.
The press box replaced the original built by students in a shop class at Onekama, including the grandfather of the current – and only fourth – coach in the Portagers’ history.
“The press box that just came down was built by the assistant coach, Mr. Foster's shop class, and my grandfather was part of that,” said Sedelmaier, who was the defensive coordinator for four years under John Neph, who with Taylor and Hunter has been the only other head coach Onekama varsity football. “The shop class built the press box and stuff on the first field and just finally now, 60 years later, we're able to make all these field upgrades. It's really been a vision for a long time, and something that I fought for, past players have fought for, the community fought for, and it's a vision that finally came together.”
Sedelmaier was a 2007 graduate of Onekama. Taylor was an assistant coach then. Sedelmaier’s grandfather, Phil Sedelmaier Sr., father Phil Sedelmaier, Jr. and uncle Todd Sedelmaier all played for Onekama during Taylor’s head coaching days.
Justin Sedelmaier has the Portagers primed for another playoff run. They are 6-2, a win tonight should guarantee them a spot in the playoffs and potentially an opportunity to host a game at the new stadium. A loss also won’t necessarily end the season for Onekama, which has reached the 8-Player Division 2 Semifinals the past two seasons. The Portagers’ strength of schedule is expected to boost their playoff chances, no matter the outcome in the regular-season finale.
Bennett Zeller leads the offense. The sophomore quarterback has completed 32 passes for 683 yards and eight touchdowns and picked up 762 yards and 12 touchdowns running the ball. His favorite target is junior Jason Sedelmaier, who has 11 catches for 260 yards and three touchdowns. The next rushing leader behind Bennett is Caleb Porter, also a junior, with five touchdowns while averaging 54 yards per game.
On the other side of the ball, Onekama is led once again by senior Ryan Hrachovina, an all-state defensive linemen last season. He has been credited 103.5 tackles this year – with 22 tackles for a loss and 18 sacks. He blocked a kick and ran it in for a touchdown earlier this fall. He’s also forced a fumble and recovered another.
Jason Sedelmaier also has been a big contributor defensively with 37 tackles, including four for a loss and one sack. He leads the team with 11 pass breakups and has an interception and a fumble recovery, along with a forced fumble.
The Portagers’ only loss last season came in a Division 2 Semifinal to Felch North Dickinson. Coach Sedelmaier is ready to build on the support of Onekama’s former players and coaches as his team prepares to make another run.
“To get to see them all coming back, wearing their replica jerseys and supporting us while we get a look back at some of the history and honoring that history was great for the kids to see,” Sedelmaier said. “That team was the first team to ever go undefeated in the regular season, and they're still the only team that's ever went the entire season total undefeated.”
