Summary: I don't think a player's stock has fallen on my board over the summer more than Heyward's. I went into the summer expecting to see a first-round pick on tape, and instead I now see a second-rounder. He gets dominated by inferior competition and should be more dominant on a more consistent basis when you factor in his size, strength and talent.
Heyward's best fit by far at the next level is the 5-technique position (3-4 DE), and I just don't see him being an impact pass rusher at 4-3 left defensive end. Heyward needs to step up in his senior year if he wants to be a top 25 pick. As I mentioned previously, Heyward is starting the 2011 season with a second-round grade on my board.
