I think the O-Line will be fine. What others say here about the need for the QB to play decent and a need for WRs to step up is true. However, after looking at a Cincinnati video in another thread, something hit me. We know Butch & Co. have had the RBs hold the ball near the chin. Being no expert, I hadn't thought much about it. But on the video I saw how much harder it is to strip the ball when held this way as opposed to letting it sling in a natural running motion. The QB was chinning it, the WRs were chinning it, didn't see much RB activity. Well, anyway, I figure if the RBs hold onto the ball, the OLine plus our decent RBs will be big in our season. The QB will have less pressure.
I think the line has something to prove twice over. One, that they are as good as advertised. They're seniors and this is their last chance to up their pro stock. Those boys are coming to play. The RBs darn well better take advantage of the Oline's 'tude.
If what we're hearing about the conditioning program, I think the defense will be ready, willing, and able to make up for our thinness in certain areas. They will up overachieving.
