In the updated first round mock draft at Mocking The Draft, the Green Bay Packers select Ohio State DE Cameron Heyward. He's a player I liked in college, and he'd add depth on the defensive line after the expected departure of free agent DE Cullen Jenkins.
On the other hand, he's coming off surgery, and drafting a rehabbing defensive lineman in the first round gives me DE Justin Harrell flashbacks. That's quite the generalization on my part, but it's what came to mind. On a more rational note, after drafting DE Mike Neal and DE C.J. Wilson last year, defensive end doesn't seem to be the biggest area of need.
