Maybe this is where we're heading with Lucky, I don't know. But, it seems to me that we need to use Lucky like USC uses Reggie Bush. Bush doesn't carry the ball a ton of times, but he still gets 100+ yards a game. Where he's at his best is when he's also used as a receiver. With 4.3 speed, we need to be using Lucky like USC uses Bush. Glenn is the type of back that can carry the ball 30+ times a game, but Lucky is the type of back that can burn you down field catching the ball.
Maybe Lucky can't catch, maybe he doesn't know the offense well enough, or maybe there's something else going on; but he does seem to have Bush-like qualities. Hopefully these two younger backs can keep getting more playing time without taking too much away from our rock solid leader Ross.
