Mel Kiper ranks the top five juniors and draft-eligible sophomores across every position. Each is ranked as a potential NFL prospect, though all should have the option to return to school for another season.
If James Laurinaitis had declared for the 2008 NFL draft, he likely would have been a top-10 pick. Instead, he chose to return to Ohio State for his senior season and is Mel Kiper's No. 1 player heading into 2008.
