On the quick-snap near the goal line, I think that's something Josh has to drill out of himself. The quick snap works sometimes, but this wasn't a good situation for it, given the clock situation. In addition, the Pats frequently try coming back to the run right after a successful run. I've seen it a lot this year. I'm sure the opponents have seen it a lot, and get themselves ready for it. The runs are frequently not successful, or have limited success.
Something that might work better is a play-action pass, where the defense sells out to stop another run, and Gronk, Wes, or Deion are wide open on the other side of the field.
It will be interesting how the defense changes to play Indianapolis. If they can change.
