Ok, I'm coming around. Some of these highlights of his are SICK. Dude has this weird ability to just subtly change direction at top speed -- he doesn't break down and lose momentum. His shiftiness seems always to keep him headed north-south. On several of the plays I saw, he gets great yards-after-catch without ever giving serious ground
(for instance at 1:05 here
I like the fact that he has elusiveness without having to run around potentially losing yardage. Might be a beast on a reverse or (dare I say?) a bubble screen. As Jerome Bettis would say, he has a real ability to "get skinny." No pun intended.
Also he can do that patented Mendenhall spin about a billion times faster and more effectively than Mendenhall too.
