Latest on Kolb vs. Manuel

For the Buffalo Bills to enjoy any sort of success on offense this season, it'll most likely be as a result of their dynamic duo of RBs -- C.J. Spiller and Fred Jackson -- taking control. Neither of their options at QB -- veteran Kevin Kolb and rookie EJ Manuel -- have stepped up and taken full control of the position thus far with glowing performances in spring practices, and there may not be any of these magical displays when we get to training camp, either. But, they do have to pick someone to start, so what's the latest on the battle between the two?
