Tenth in a series examining key players departing, staying and arriving at Big Ten schools in 2010.

Going ...

Brandon Graham, DE: Graham didn't win Big Ten Defensive Player of the Year honors last fall, but no defender in the league looked more dominant than No. 55. His numbers were simply insane: 26 tackles for loss, 10.5 sacks, two forced fumbles, two blocked kicks, one recovery of a blocked punt for a touchdown. Graham's stats and leadership will be sorely missed up front.

Donovan Warren, CB: Michigan's secondary wasn't good in 2009, but it could have been even worse without Warren's contributions. He led the team with four interceptions, including a pick-six at Iowa, and also topped the chart in passes defended with seven. Warren earned first-team All-Big Ten honors from the media.

Staying ...

Stephen Schilling, G: Schilling has been through it all at Michigan, and he'll help anchor a line that should be one of the Wolverines' strengths this fall. An honorable mention All-Big Ten selection in 2009, Schilling has started 36 of his 37 career games at tackle or guard. ESPN's Mel Kiper ranks him as the No. 4 senior guard for the 2011 NFL draft.

Troy Woolfolk, CB: If Michigan's defense turns things around this fall, Woolfolk figures to play a major role. The converted safety has built up his confidence at the cornerback position and brings both experience and talent to the secondary. After a strong spring, Woolfolk will step into Warren's spot and cover the Big Ten's top receivers.

Coming ...

Cullen Christian, CB: Michigan has an obvious need in the secondary, and Christian should see the field this season, especially since Demar Dorsey isn't coming to Ann Arbor. Christian is an intelligent player with good size who can read quarterbacks and understands coverage schemes.

Will Hagerup, P/K: Graham and Warren are major losses, but Michigan really will miss All-American punter Zoltan Mesko this fall. The Wolverines also lose kicker Jason Olesnavage, so Hagerup will make a major impact in 2010. Like Mesko, Hagerup has excellent size (6-4, 210) and was heavily recruited coming out of high school. Michigan's specialists struggled this spring, so Rich Rodriguez will turn to Hagerup.
