Bush relied on his quickness to just flat out beat everyone up the middle or around the corners. His biggest weakness comes in his lack of strength.
Bush used lots of open room to be able to make his shifty moves and get around people. In the NFL, where holes close much quicker, I just don't see that happening.
Bush doesn't break tackles well, a lot of that is due to his poor strength.
All in all, he reminds me of Brian Westbrook.
No, JP would be stupid. So would anyone else at the NFL level that said that.
