I think Sanders will give Brock a run for his money, but Brock will probably start. It might be similar to when Hall was a freshman when Johnnie Lang and/or Nwangwu and even Sheldon Croney played or started before Hall for the first few games, but then Hall took over as starter about 4 games in. I fully expect Sanders to be starting by the end of the season. Sanders has run a 10.7 100 meters, so maybe it will be a bit of a thunder and lightning situation between he and Brock. If I had to chose between a speed back and a power back, everything else being equal, I'd go with speed every time.
