O-line seldom gets noticed or credit when things are going well, but if things don't go well, are first to catch blame by the clueless.
This was a very good O-line: Cam, who had six seconds in the pocket a few times this season, also missed wide open receivers early a lot and threw some Ints. Our warrior, best receiver, had two bad fumbles and a couple of drops at the end of the season. Our RBs had some fumbles; nobody played error-free because the other team is schemeing to cause those errors.
Lots of things you could look at; this ain't where to start.
