That's not groundbreaking stuff, if a QB has a poor OL and poor run game it's going to be difficult to pass especially adding in the problems we had at WR. It's a simple fix to me, fix the OL. Draft or sign a RT and we'll be ok. Remember, Mangold was playing hurt most of the year as was Brandon Moore and Wayne Hunter didn't adjust to being a full time starter. Assuming Moore and Mangold are healthy, Brick is back to his normal self and we get better RT play this OL should be MUCH better.
of course he will never be Brady or Manning but you don't need a Brady or Manning to win. Backup level material QBs don't go to back to back title games, even in a "bad" year this year we were 8-8. If your QB is that bad w/ as bad as the team was around him you aren't going 8-8.
