Joe Marino may have explained it. The Bills most likely game planned for heavy man coverage as that is what Aaron Glenn Defenses are known for. The Jets played counter tendency and went to more zone coverage. The Bills were not this early in the season ready to just flip the switch to deal with it. The Bills also played a lot of 3 TE sets which is a new wrinkle for them.
Keep in mind this early in the season Josh is still setting chemistry with Palmer. They are starting to connect which will open things up eventually.
