Just food for thought...but if hes capable if dropping wait and maintaining it...dont most teams making the switch to 3-4 make their DE's OLB's when possible?
I think that is usually when they are of the lighter, speed rushing variety ends.
When Cam came into the league he was a powerful, anchoring, Strong side type End who wasn't really projected to be a great pass rusher. I think that's why so many feel strongly that he can excel as a 34 End.
