I have been following Nebraska's practices and have been wondering how our running backs are doing. The available media like Husker's HQ and huskers.com have chronicled Rex Burkhead to a fault, so I know Burkhead is having a good summer preparing for game with Chattanooga - Tennessee on Sept. 3. Still, I was wondering how our other backs were doing. I have seen a little bit on the blue chip recruit Aaron Green from Texas. How is big Collins Okafor? I have it in the back of my mind that this guy as force to be reckoned with. 6-0, 230 with good speed. I'd like to see his power assist Burkhead. How are the other backs besides the talented Burkhead doing? I have heard very little.
