Big Ten rankings: No. 9, Jonathan Brown

Why he's here: A high motor, speed and a little bit of recklessness helped Brown achieve a breakout season as a sophomore. He had some huge performances, including the Arizona State (3.5 tackle for loss, interception) and Ohio State (17 tackles, 1.5 sacks) games. Only teammate and Hendricks Award winner Whitney Mercilus had more tackles for loss in the Big Ten, and Mercilus got to line up a whole lot closer to the line of scrimmage. But Brown covers a whole lot of ground in a hurry.
