I can't get over some of the homerism. How does adding Marshall not make them exceptionally better? Regardless of his off field stuff that everyone points to, he has produced at a high level every year. He had a Pro Bowl season with Kyle Orton. Sanchez has much more potential than Orton, and Sanchez will improve from last season. With that o-line and running game, it makes it easier on Sanchez to throw, especially with play action.
There is nothing wrong in the locker room with that defense. All of those guys love playing for Rex and love to talk because Rex evokes confidence, and they all follow suit. Revis and Cromartie are perfect CB's for that type of defense. Jenkins coming back is also a boost. Even if he's not the same player he once was, he's still big enough to just occupy blockers and stop the run like Wilfork.
Either way, we have a lot of work to do.
