Personally I always try to take RBs who are the focal point of their offense. Rudy, Dominic & Westbrook all split time in the backfield. Portis is not going to be the same after the injury this year (didn't they just trade for TJ Duckett?). Cadillac, Jackson, James, Jordan, Barber & Mcgahee are all in the same 2nd tier of solid RBs IMHO. Tomlinson, Alexander and LJ are in a class all their own in the 1st tier.
