If the Offensive coordinator lets them get dominated by not going into actual running formations, we will have a problem. My guess is that when BJ is back there, we will see the 2 TE and FB set more often. They hardly lined up with that at all against the cowturds, Gil decided that they could not power run without BJ so they hardly even tried.
That reason alone, if there is No-BJ we have no chance. Unless of course TC smacks Gil upside the head and forces him to let this team do what it does best - kick ass.
