We benefited a lot from Justin Houston being basically a nonentity, but the OL did its job against a front 7 that's still pretty good even without him.
If we're looking to assign credit for the improvement in pass protection over past weeks, I think it's primarily thanks to Edelman. When you're getting the ball out that quickly, the OL 'just' has to not suck to do its job, and to their credit they didn't suck. The Pats still don't seem to be much of a threat to run the ball, and I think any defense feels good about its chances of getting to Brady if he holds onto the ball for more than 2.5 seconds or so, but we've got a good shot at bringing home a fifth Lombardi if the line can just replicate what it did on Saturday two more times, so I'm happy with it.
