Which new Wolverine is most likely to have an early impact?

Michigan will have some holes to fill on defense this fall.

Michigan will enjoy the return of a huge number of starters in 2016, but there is one position where an exodus has occurred: Linebacker. 

All three starters graduated, and James Ross was listed as the primary backup inside while starting on the outside. 

Devin Bush Jr. is not the highest rated Michigan recruit, but he could be walking into a situation that calls for him to see the field early. 

A 247Sports consensus four-star recruit, the Pembroke Pines, Fla., native only measures 5-foot-11 but packs some wallop with his 224 pounds. 

Older available high school tape shows a player who can run and hit if linemen can keep him clean. 

Rivals has him as the No. 7 inside linebacker in the country while Scout and 247 both have him in the low teens. 

As an early enrollee, Bush should get plenty of chances to prove he is worthy of early playing time this fall. 

Second choice: Kareem Walker 

A 6-foot-1, 210-pound running back from Wayne (N.J.) De Paul Catholic, Walker is also an early enrollee for the Wolverines. 

He was considered one of the best running backs in the country heading into his senior season but Rivals and 247 Sports both dropped him significantly in recent re-rankings. He remained a four-star in both of the latter services and a five-star per Scout.com. 

Regardless, the former Ohio State commit had a lot of big-time schools after him and gives Harbaugh another option at a position that was never quite settled in 2015. 

De’Veon Smith proved to be productive when healthy, but Walker could bring more big-play ability to the position, which would lesson the temptation to take Jabrill Peppers away from the defense.
