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.”

Transformed Shores Continues to Rise
September 8, 2015

Special for Second Half
This is not your father’s Muskegon Mona Shores football team.
Or even your older brother’s.
This is not the team that went its first 51 years of football without making the MHSAA playoffs and whose only traffic jams leaving its parking lot occurred early in the third quarter – when the band was done performing.
Heading into one of the state’s marquee Week 3 matchups at home against perennial Division 1 powerhouse Rockford, Shores is looking to snap a 10-game losing streak against the Rams, which has included some forgettable affairs like a 49-7 loss in 2000 and 10-7 loss last fall, the Sailors’ lone regular-season defeat.
“Great job tonight,” Mona Shores coach Matt Koziak told his huddled players last Thursday night, allowing them a few seconds to enjoy their 2-0 start and a dominating 55-14 win over host Fruitport, before quickly shifting gears.
“But now we have Rockford coming to our place. We can’t make the mistakes we made tonight, or they will make us pay for it. We have to play top-notch.”
The emergence of Mona Shores as a power has changed the landscape of football, not only in the Muskegon area, but West Michigan as a whole. As other Muskegon-area schools struggle with declining enrollment – most notably Muskegon High, Muskegon Heights and Muskegon Catholic Central – Mona Shores is now the largest school in Muskegon County and a legitimate force, bursting onto the state scene with a memorable run to last year’s Division 2 championship game at Ford Field.
After putting up 55 points in back-to-back wins over Holland West Ottawa and Fruitport to open the season (and with their defense not allowing a single point), the Sailors are showing that the 2014 season was far from a flash in the pan.
“Last year we were the hunters; now we’re the hunted,” explained senior quarterback Tyler Trovinger, who set a school record with six TD passes in the Week 2 win over Fruitport. “We have to be great because no one is looking past us anymore.”
The Sailors’ fortunes, and attitudes, began to change in 2011 with the hiring of Koziak as head football coach. He turned out to be the perfect choice, as a 1994 Mona Shores graduate who cut his coaching teeth at Muskegon High School under Tony Annese, serving as offensive coordinator when the Big Reds won MHSAA titles in 2006 and 2008 and as head coach for one year in 2009.
His words upon taking the Mona Shores job in 2011 were prophetic:
“I'm tired of people badmouthing my school,” Koziak told The Muskegon Chronicle at that time. “I’ve heard people say the Shores kids are cake-eaters. It’s not true. There are a lot of blue-collar kids and families there. I’m excited to change the football culture.”
While Koziak knew Shores football history, he also was smart enough to recognize changes that needed to be made – beginning with the installation of the spread option, veer attack which was so effective across town at Muskegon High.
The most notable player was quarterback Tyree Jackson, who Koziak inserted into the starting lineup as a 5-foot-9 freshman. After struggling mightily and making people question whether the new coach was running the wrong system, Jackson sprouted to 6-4 and started throwing to targets like Asantay Brown and Marquon Sargent.
Brown is now a starting safety at Western Michigan University, Sargent is at Grand Valley State University and Jackson is a freshman quarterback at the University of Buffalo, but the Mona Shores system and the athletes haven’t missed a beat.
Trovinger (5-11, 200 pounds) has stepped into Jackson’s big shoes and possesses a cannon for an arm and terrific running ability.
Trovinger’s passing options are nothing short of an embarrassment of riches. Three of the starters in the Sailors’ four-wide attack have already made Division I college commitments – Hunter Broersma (6-2, 190) and Darece Roberson (5-9, 165) to Western Michigan and Kobe Burse (6-3, 205) to Miami of Ohio – with the fourth starter being dangerous Deandre Oakes-Owens (6-0, 175), an all-league selection as a defensive back last season.
“We have a ton of weapons, no doubt,” Trovinger said. “When we’re all focused, we’re a force to be reckoned with.”
The defense is led by two more senior standouts who could possibly sign with Division I schools. Dom Shermeta (6-0, 215) is a Chris Spielman clone at middle linebacker and a battering-ram fullback, and Christian Boyd (6-2, 280) is a run-stuffer at left defensive tackle.
Koziak said a big part of the Shores turnaround is the supportive administration, notably seventh-year athletic director Ryan Portenga, the outspoken, energetic and unapologetic leader of the Shores athletic program.
Portenga has written a book about the Mona Shores football turnaround and the storybook 2014 season, entitled: “Flipping Football: A True Story of Resilience and Transformation.” The book, which costs $20, will be released Friday, in conjunction with the Rockford game.
“It’s a story that needed to be told,” said Portenga, who noted that half of the proceeds from the sale of the book will go to the Shores athletic program.
So … with all of this talent, all this excitement, all this momentum (even a book!), are the Sailors ready to take the next step and knock off the biggest kid on the block – Rockford? Or will the Rams’ mystique win out again?
It’s the same question Muskegon-area residents were asking last October, when the upstart Sailors traveled to historic Hackley Stadium to face the Big Reds, which had downed Shores 14 games in a row. Shores matched the athletes for Muskegon and made believers out of many in a convincing 48-27 victory.
While every eye in Muskegon was on that game, many eyes from around the state will now be on Sailor Stadium when a senior-laden Rockford team comes to town Friday, looking to swat away the latest challenger to its perch atop the West Michigan football heap.
Rockford (1-1) is coming off a 47-0 romp over visiting Holt, and will bring its usual big offensive line, bevy of running backs and unparalleled special teams – especially senior kicker and punter Quinn Nordin, who has committed to sign with Penn State University.
The Rams have extra motivation as coach Ralph Munger has 299 career coaching victories over his 36-year career, the first 12 spent at Frankenmuth and the past 24 at Rockford. His next win would make him the 11th coach in state history to register 300 wins.
Shores is not motivated to deny Munger, but rather to avenge last year’s 10-7 loss at Rockford. In that game, Roberson scored on a 79-yard run on the first play from scrimmage, but failed to score again, fumbling twice in the fourth quarter.
With a huge crowd expected for the rematch, Koziak said his players will be motivated to come out and not let another game against the Rams slip away.
“We talked about how Rockford beat us last year,” said Koziak, who is assisted on the varsity level by Brian Sikkenga, Holsey James and Aaron James, Chris Hilliker and Kyle Brott. “They have that in the back of their minds that they let one get away, and that’s motivation for them.
“I think there’s a new energy for football with what we’ve been able to build the last four years. The community has waited forever for this. They’re ecstatic.”
