Michigan's Warren declares for draft

Michigan cornerback Donovan Warren has become the second Big Ten junior to declare for the NFL draft.

Warren, who had hinted he'd turn pro for quite a while, made it official on Sunday.

"I am confident in my abilities to play any receiver at the next level," he said. "I am hoping to be drafted in the first round."

A first-team All-Big Ten selection, Warren recorded four interceptions and 11 pass deflections, finishing among the league's top 10 in both categories. ESPN's Mel Kiper Jr. ranks Warren as the nation's No. 2 junior cornerback.

Warren's departure leaves Michigan without its top two defenders for 2010, as defensive end Brandon Graham has exhausted his eligibility. One of the league's worst defenses needs to identify playmakers up front and in the secondary.
