@cplach Hargrave can play both DE and NT, and we also picked up Mathews from the Chargers. Both are vast improvements over Cam Thomas and Cliff Geathers. As for RB I agree that we're going to need some depth there, maybe rounds 3-5.
Outstanding ability to adjust, mirror, and recover
Elite agility and speed
Great in pass protection
Nice awareness; head on swivel and picks up blitz
Good hands; extends and locks on
Light on his feet
Solid run blocker
Love his footwork
Ridiculously high upside
Room to develop strength and body mass
Elite skill set
Inexperienced - only 17 career starts
Too upright in pass protection
Natural knee bender?
Plays with narrow base
Legit durability concerns
Summary: Consider Bruce Campbell the Jason Smith of the 2010 NFL Draft class. His stock will be soaring through the roof once we get to the Combine, however, he is more of a natural pass protector than Smith. With more experience, he could become a Pro Bowl left tackle at the next level. Of course, you have to consider his long list of injuries, but he'll likely be taken in the top 16 picks.
Player Comparison: Branden Albert. Albert and Campbell have great physical tools, but I think Campbell is more of a natural left tackle. Both were raw offensive tackle prospects.
