Indiana suffered a pair of blows this week with linebacker Marcus Oliver and running back Devine Redding opting to forego their final seasons in Bloomington to instead take shots at making NFL rosters.

Turnover is natural in college football, and it’ll be up to new faces to fill in.

In the case of Oliver, that means replacing a starting linebacker who registered 96 tackles, 15.5 of which went for loss, and four sacks. He was also in charge of aligning the defense on the field.

Redding took 253 carries for 1,122 yards through 13 starts at running back. He was a consistent rusher throughout his time in Bloomington, becoming the first rusher to go for back-to-back 1,000-yard seasons in 25 years.

With those two on the way out, it’s time to see who’s on the way in.

Welcome to the Camion Patrick era, two years after we thought it would start.

At least, that’s the plan.

Patrick, a JUCO transfer from East Mississippi Community College, came to Bloomington as a receiver the summer before the 2015 season but was forced to sit out for academic reasons. In the meantime, he played on the scout team that season at a few positions, including running back.

It was there, at tailback, that Patrick found his stride. Reports from players and former head coach Kevin Wilson alike suggest Patrick regularly tore through the Hoosier defense to the point where he was asked to slow down. It earned him high praise.

“Best player on the football team is Camion Patrick,” Wilson said after beating Purdue in 2015. “You haven’t seen him yet. He’s really good.”

Patrick made his debut this past season at receiver after an ACL tear in spring practice spoiled all chances of him getting into the backfield. He appeared in 10 games, making six catches for 154 yards and a touchdown. He also took a few snaps at running back but was again injured near the end of the season, though the extent is still unclear.

After Patrick, the Hoosiers have a wide range of options.

Mike Majette, a rising junior, is a speedster who still seemed to be learning the pace of the game before getting hurt after eight games. Tyler Natee, a rising sophomore, proved himself as a bruiser in the wildcat.

Rising sophomore Cole Gest showed promise early but only got through three games before a season-ending injury. Rising redshirt sophomore Devonte Williams, after returning to running back from cornerback, took 48 carries for 167 yards and also served as the primary kickoff returner.

IU running backs coach Deland McCullough doesn’t need to prove himself. He’s sent three consecutive juniors into the NFL Draft and has industry-wide respect for his job coaching up rushers.

He’ll figure something out. But it starts with Patrick.

Unlike with Redding-Patrick, there’s no clear replacement for Oliver at linebacker.

That isn’t necessarily a bad thing. It just needs to be addressed.

Oliver, a defensive captain and undisputed voice of the locker room, missed Indiana’s Foster Farms Bowl game with an injury. In his place, rising redshirt junior Dameon Willis got the start and made four total tackles. He could be a favorite to take the spot.

But that’s just the beginning of linebacker coach William Inge’s options.

JUCO transfer Mike McGinnis, who has two years of eligibility remaining after joining the program this semester, proved himself as an All-American at a lower level and could have a say in the job. So could Chris Covington, a rising senior, who picked up a sack against Utah after appearing in all 13 games.

On the field, Inge might need to piece together a few players to fill in for Oliver’s production. That seems possible alongside rising senior All-American Tegray Scales.

But off the field may be another story. His leadership will be missed.

Someone else needs to step in.
