While Gurley may help, I do really hope that fans aren't expecting this kid to carry the team.
It's not realistic and it's not good to put all that pressure on him. The team around him needs to step up, and Foles can't have games like he had last week. He needs to be sharper. Yes--the o-line has to improve, of course. But Foles does need to move a bit better in the pocket and certainly throw better passes.
And if I was Fisher I would certainly limit him against the Steelers so we aren't saying right out of the gate, "Okay, Todd...it's all on you."
That's a recipe for failure.
Gurley has to be a part of the offense--a huge part, for sure--but he can't be THE offense.
