I think it would be a combination of the RB and the line playing off of one another - a systematic synergy if you will.
I think the players on the line are decent players; Avila looks like he could become at least a solid pro bowl type.
I just that right now, as a unit they haven't put it all together. If they stay pretty healthy they will improve I'm sure; I just don't know how much.
The RBs are not every-down backs, but they are all the same size with the exception of Freeman.
I like Williams but he's going to wear down at the pace that he is being deployed.
