If we are without Rex for a month, it not only affects the ground game, but punt/KO returns as well. I'm sure Paul can handle it, but if he muffs another one who is Bo gonna put in?
I was scanning the posts to see if anyone would touch on the punt return thing. This is a big deal. First, the reason Burkhead, a true freshmen, was made #2 at running back was because no one else stepped up. This means the coaches aren't comfortable with the other guys. Playing rb is more than just run through this hole or that one. Second, problems catching punts, who do they turn to? Rex. Coaches put Rex in because he doesn't make mistakes, the others have. Mistakes lose games.
