The understudy has become the star for the Muskegon Mona Shores football team.

James Gilbert was supposed to be “the other guy” this season, the receiver on the opposite side from Division I recruit Damari Roberson, who has committed to Western Michigan University.

But the cast list changed in June when Roberson, a 3.6 GPA student who at one time had more than 17 college football scholarship offers, tore the ACL in his left knee for the second time in nine months during a non-contact drill.

“That’s when everything changed,” explained Gilbert, who always had considered himself a basketball player on the football field. “The coaches and Damari sat me down and told me that I had to be the man, that I was the only one with the same type of ability that could take his place. They basically challenged me.”

Shores coach Matt Koziak said Gilbert, a 6-foot-2, 181-pound senior, has always had the physical skills. But since Roberson went down this summer, he has been focused, motivated and driven like never before.

The result has been an incredible senior season for Gilbert, who has 51 catches for 1,172 yards and 10 touchdowns. His emergence as one of the top receivers in the state enabled the Sailors to climb all the way to No. 1 in Division 2 in the final Associated Press state rankings.

Mona Shores (9-1) will put its top ranking to the test Friday night in the MHSAA District championship game against visiting Ottawa-Kent Conference Black rival Jenison (7-3). The two teams engaged in a shootout just three weeks ago, with the visiting Sailors escaping with a 49-42 victory.

Gilbert played a huge role in that win, with six catches for 93 yards and a touchdown, coming up big once again when his team needed it most.

“JG has been unbelievable all year,” said Koziak, who has a 60-26 record in eight years as the Sailors’ coach, highlighted by a run to the Division 2 title game in 2014. “With all of the injuries we’ve had, he’s kind of been the one constant. When we’re scratching our heads, we can always throw it up to James.”

Coming into the season, Koziak knew he had senior battering ram running back Sincere Dent (5-11, 217), who has delivered with 118 carries for 1,082 yards and 20 touchdowns. The problem is that Dent has played in only seven games and his playing time was reduced in several others due to shoulder and ankle injuries.

Junior quarterback Caden Broersma (6-3, 206) also has been outstanding, completing 81-of-112 passes (72 percent) for 1,547 yard and 13 touchdowns, with just one interception. He also has rushed for 621 yards and 12 touchdowns.

The most surprising statistic for Mona Shores is that Gilbert has accounted for 76 percent of the Sailors’ receiving yards.

“I’m not surprised, because he’s always had it in him,” said Roberson, who has remained a key part of the team, attending every practice and serving as another assistant coach for Koziak. “I always learned from him in basketball, and I taught him everything he knows about football. With me being out, he’s had more of a chance to show what he can do.”

Gilbert is starting to garner more and more interest from college football programs, with Saginaw Valley State, Ferris, Davenport and Mount Union (Ohio) showing the most thus far.

Gilbert wasted no time proving he would be “the man,” showing his big-play ability with five catches for 159 yards (32 yards per catch) and a touchdown in a big 48-38 win over East Kentwood in the season-opening Gridiron Classic at Grand Valley State University. East Kentwood hasn’t lost a game since.

He also came up big in the cross-town showdown Oct. 12 against unbeaten Muskegon, which is ranked No. 1 in Division 3. Gilbert caught six passes for 118 yards, including a one-handed, 28-yard touchdown grab. He also threw a 31-yard touchdown pass to Andrew Swick on a trick play in that 55-35 loss.

And Gilbert was at it again in last week’s narrow 34-28 District win over Grand Rapids Forest Hills Central, catching five passes for 120 yards and a touchdown. He sealed the win with an interception as the Rangers were driving for a potential game-winning score in the final minute.

“It’s been fun, but we know we still have a lot of work to do,” said Gilbert, who has impressed opposing coaches with his ability to come down with big catches in traffic. “Damari and I have been playing with each other and against each other since Little League, so I kind of feel that I’m playing for him this season.”

As for Roberson, he still believes that a season that began with a nightmare injury could have a storybook ending – both for the team and himself.

Roberson (6-2, 194) said his rehabilitation is going great and his possible return date from the injury is during the week of the MHSAA Semifinals. So there remains the possibility, if the team keeps winning, that Roberson and Gilbert could line up as opposite wideouts, like the original plan.

“Stay tuned,” said Roberson, who is on pace to graduate early in December and then enroll at WMU in January. “After all that this team has been through, with all of the injuries, that would be the perfect ending.”
