Hargreaves looked awful vs. Michigan. He was boxed out often like a basketball rebounder. Hargreaves is active but he plays so small he simply can't cope with bigger receivers who know how to use their body. He was also burned badly on double moves a couple times in that game.
Still, Hargreaves' overall career and talent level will equate to high to mid first round pick, even if he's no longer considered the best cornerback on his own college team.
All of Florida's touted defenders played poorly in that bowl, like they wanted no part of facing a north/south power based pro offense as opposed to somebody like Kentucky.
