Bush is awful if the opponent has any room to maneuver. If so, any bit of wiggle is too much for him.
It's never going to change. He'll be brutally exposed in the pass happy NFL with all the sophistication. This isn't a matter of great talent without knowledge of how to apply it. Bush lacks change of direction. Unless the play is smack in front of him he can't cope.
Our touted secondary guys all have basic flaws, despite the high school hype. Burns is too leggy. I still have hopes for him but it's obvious the early freshman hopes were overblown. Howard is too small and soft and seldom finds the ball. If he does find the ball he doesn't make a play on it.
