What coach has the most to prove this season?

Coughlin: Can he take the Giants back to the playoffs?
Shanahan: Can he keep his QB healthy for an entire season, and will they repeat?
Chip Kelly: Will his offense and philosophy succeed in the NFL?
Garrett: Will managing less of the playcalling make him a better coach?

But I think it's a worthy question, and laid out well. Personally, I think Garrett's on the same hotseat Wade Phillips was on when his team gave up on him. I don't think the cowboys will give up early, but if they start 2-4 or worse, the team may spiral out of JG's handle. And no talk of process will cut it when you have been in his shoes.
