Michigan Football Recruiting: Commitments Who Will Make Instant Impact Next Fall

College football signing day is only three weeks away, and while Michigan pretty much has its 2012 class set, it could still grab a few more prospects in the coming weeks.

With that being said, however, it's not too early to take a deeper look into the current class and determine which youngsters will have the biggest impact next season.

Here's a quick look at three players who could earn "Rookie of the Year" honors for the Wolverines in 2012-13. 

Kyle Kalis, OT

According to Rivals, Kalis is Michigan's lone 5-star prospect and is ranked as the 21st-best recruit in the nation.

Michigan struggled at times protecting quarterback Denard Robinson, although he sometimes hid that fact with his ability to escape pressure. Still, the Wolverines could use some depth on the offensive line, and Kalis has the ability to immediately contribute.

Standing at 6'5" and 302 pounds, Kalis has the size, strength and technique to step in at tackle or guard, making him a nice commodity. He was extremely impressive at the Army All-American Bowl last week, a game in which he mostly played guard.

Kalis showed he can go up against the nation's best with ease. 

Ondre Pipkins, DT

Pipkins battled injuries throughout his senior season, but he remains Michigan's best defensive tackle (out of two) recruit. 

Rivals ranks the big man as the 59th-best prospect and seventh-best defensive tackle in the country. ESPN doesn't rank him quite as high, but that doesn't change the fact that he can disrupt the run game with the best of them. 

Pipkins received Rivals' "Bull Market" Award after the Army All-American Game, after which he "raised his stock the most...(and) has a chance to move from outside the top 50 to possible 5-star status."

The Missouri native possesses good strength and quickness, attributes that will help him step in at the college level immediately. Michigan struggled against the run at times this season, and he will help the Wolverines in that facet right away.

Joe Bolden, LB

The Wolverines have a slew of talented linebackers coming in this class, but Bolden is the most likely to contribute right away. 

Bolden is the prototypical, hard-nosed linebacker who has an intelligence and instinctiveness that can't be taught. He combines that with good athleticism and terrific tackling-ability.

The 4-star was recently called the "best tackler" at the Under Armour A-A Game.

Bolden has drawn comparisons to Paul Posluszny of the Jacksonville Jaguars, and Bolden should have a successful college career in Ann Arbor.
