Figure they are probably only going to get 3 possessions in the 4th Quarter, they have to scored TDs on every drive obviously.
They might need to start going for it on 4th down when past their own 40.
If it's still 20 points difference with 10 minutes to play then it'll be 4th down tries on every play - they won't be able to afford to see 3 minutes off the clock every AZ possession, even if the defense holds them to all 3-and-outs.
