He also needs to work on his hands and technique, his entire football life thus far has been predicated on his speed and athleticism (which are off the charts). He needs the refinement aspect of his game which will come with time. If he isn't quite fully there yet or developing it to be used without rely back to his old ways - it is prudent to clip his time a bit so he doesn't feel overwhelmed and has a chance to slow down and think a bit. Typically when you are drafting blue chippers you know there is a bust potential (it happens every year), but you are betting on the intangibles you can't coach up - speed, athleticism,and size etc. I need to say this because someone will be a jerk at some point, no they usually are not scrubs either in the college level.
