I think that even with this line, having Anquan Boldin in his prime back in this offense would make it legitimate. Not awesome, but we'd score more than 20 points per game, which would put us in playoff contention.
The biggest problem that I see on film is that our WRs get pushed around a little bit off the line, and the QBs have struggled to buy the extra half-second it takes for the receivers to get back into their routes. If you push Andre Roberts back into the slot and put in Anquan Boldin into the lineup, I think that everyone gets much better.
