Also realize that they played an almost perfect game. That offense had to play it basically perfectly, executing key 3rd down after 3rd down, Kupp/Nucua made some INSANE catches all while extending drives, almost doubling TOP vs the Bills.
Despite all that, the Bills almost came back and difference here was a blocked punt returned for a TD. So yeah I think our offense is better because to beat the Bills you have to play a perfect game.
