Just got around to watching Brown's Hudl. While he lacks the elite speed of Jamaal Charles, he's plenty fast. Seems to find his way through the line with good vision and has a little wiggle to get through those tight spaces.
What really stood out to me, though, was his short area burst, his acceleration on the run and from a stand still. He gets going from a standing position in the backfield to full speed in just a few steps and hits the line just as the holes are starting to develop. I watched Ced Benson in high school, and he had that same burst. Zero to sixty real fast. Now, Benson lost some of that in college, I believe, after bulking up. But that fast-twitch ability is something you can't teach. Brown looks to have that.
Besides top-end speed, Jamaal's killer move was being able to cut sharply at full speed without dipping. I don't see that in Brown, but then I haven't really seen that it anyone (Marshall Faulk in his prime, maybe?).
Physically, I think he's got more upside than Trey Watson, though. Would sure be nice to get some long breakaway runs next year. The only thing that makes me happier than a 10-win Texas team is more wins next year and some friggin' explosive plays.
(I also like the detail that Brown's family sent the coaches fruit baskets on signing day, so happy were they to have signed with Texas. Suggests good attitude and full-on program buy-in. He'll have a good shot here.)
