When Betts has gotten reps he's looked just as bad--look at his YPC. That suggests the O-line is to blame, not the backs who've both gained 1000 yards in a season in the NFL.
Look, Gibbs brought Sunders in and gave up the playcalling and the playbook. IMO, Saunders is the O-coordinator brought in at great expense to make this O work. Now, if you really want me to believe that Gibbs is just sabatoaging Saunders, I'd like some proof. Yes, they wanted to run out the clock up 21-6 against the cards--Saunders agreed that this was the move. And they won. If Saunders wants to do something else with the O, he needs to step up like a man and tell JG what he wants. Is he such a wimp that he can't do that? Be a friggin man.
But here's my guess--you've got a combination of things from top-to-bottom slowing the O right now. Injuries, execution, AND playcalling altogether. And my guess is Gibbs and Saunders are right on the same page about how to play things. I may be wrong, but I have not seen the evidence against this. JC--who has maybe started 15 games, did not look good on the road against a top-5 D--fire the coach!
If we cannot move the ball against the Jets and teams like that on the schedule, get back to me. (I'm sure you will!

) But I think you are over-reacting to a blowout on the road against one of the best teams, from top to bottom, in the history of the league. Give it a few weeks.
