Allen has never been sacked so little, so something has changed on the line. You can see that he has a lot more time this year compared to past years, when, regular as clockwork, Spencer Brown would be beat, Allen would dodge, and the play would commence. Snap, whiff, dodge, look. This year, it's snap, look, look, look, dodge, scramble, throw, or some variation. He seems to trust his protection more, too, unlike two years ago and maybe parts of last year.
