About the OL and the running game, I think they try to finesse to much. I saw both tackles not being quick enough to lead Marshawn and Jackson when they pulled. Take for example the Marshawn TD against the Raiders, the entire OL fired up-field for an easy TD.
We have one of the biggest OL in the NFL, I think we would be much better off starting games with a more straight running style, leave the pulling and the finesse type running late in the game where the opposing defense is more tired to fill the gaps.
But I agree with you, we should target OL in the next draft, early and often.
