I agree with that with the current OL and the injuries on defense, the chances are slim.
The only real chance this team has is to get off to a sizzling start in the remaining games, which is not a strong point of this team or coaching staff. The offense needs to score touchdowns early and often, and make the other team play outside of their game plan.
If we continue with the same crappy game plan of falling behind early and having to to play catch up and defend a strong running game, we have no chance.
Realistically, Garrett is too stubborn, and arrogant to stray from his crappy game plan until its too late to control the game.
