I just watched a couple highlight videos on Youtube of Le'Veon Bell. There were a lot of big holes for him to run through, he takes a lot of runs to the outside (it will be more difficult to get outside of an NFL caliber linebacker), and I didn't see a lot of broken tackles for a big running back. He did looked quick, caught passes and used blocks well. I also didn't see any blitz pickup, so I'm not sure what he'll be like pass protecting for Ben.
I think he may have been drafted a round too early.
