The Bills exposed a flaw in the Jets' gameplan by completing so many underneath passes to Sammy Watkins. The Jets left Darrelle Revis in single coverage and he consistently gave Watkins too much of a cushion. Watkins ended up with 11 catches for 138 yards on just 15 targets. While Revis wasn't to blame for all of that yardage because there were situations where they were in zone, he still lost that matchup more than he won it.
This highlights a problem with Revis about which I discussed my concerns a few weeks ago: The Jets are paying Revis to cover number one receivers one-on-one and if he can't handle those assignments almost flawlessly, the whole defense falls apart but if you give him a more conventional role, what exactly are you getting for your money?
They could have played even more zone or given him safety support, but the idea behind keeping him in one-on-one assignments is that it enables the Jets to blitz and hopefully gives some of their best pass rushers a one-on-one of their own. This gameplan would have worked against Rex Ryan while he was with the Jets, but Tyrod Taylor is much more adept at taking what the defense gives him than the quarterbacks Ryan had and the Bills also left extra blockers in the game quite a lot to help mitigate the pressure.
