If the Bills had their true starting secondary, the Bills would have won the game.
As bad as the Jets D made the Bills O look, they still scored 20 points, and if Gilmore, McK, and Brooks were at corner, with Byrd and A-Will at strong safety where he belongs, the Jets would have been lucky to score 9 points at best.
I think the pass rush and the blitzing went out the window because the coverage was so bad, it wouldn't have been effective anyway.
