How many starting RBs are worse than Portis?

[GTripp0012]

The other point, is that if Portis finishes that run, like every other No.1 back in the league would have, in the end zone: we probably win that game 10-9, or even 10-6. Is it Portis' fault that Collins threw three straight incomplete passes in the red zone? No it's not. But it's a big, glaring missed oppertunity in the open field, and plus, it's not a shock that none of our receivers were open in three consecutive plays.
