Tebow was motivated. Sometimes all the motivation in the world can't overcome the lack of talent to perform at the NFL level.

I hate to say it but I just watched the Georgia vs Bama BCS Championship game over, focusing on Trevon Walker on each play. As a pass rusher, he got no penetration toward the QB, which reminded me a lot of Chaisson. That said, I'd almost be inclined to state both of them would be better served at playing the LB position in a 3-4 scheme. As noted, neither get penetration when lined up against an OT so their speed could be better served in blitzing schemes or 2nd level run stoppers and marginal pass coverage use.
