I just stumbled on this... Unofficial 40 Dash Time for Amukamara at Combine.

One reason mentioned quite a bit about Prince slipping down draft boards was his lack of elite speed... He put up a 4.37 according to this.  I think he proved that, without pads, he can run a time that would make him more than competetive at the next level.  I think he just solidified himself as the #2 CB--not that I doubted he wasn't but i've seen Smith going before him in some mocks. I think his performance just took us Lions fans out of the running for aquiring his services... Any thoughts about this?
