If you put a gun to my head, I think that Allen made it, though I can't say that with 100% certainty. The biggest thing that I couldn't understand is that Buffalo had issues with that play the whole game. Why call it again when you can run Cook who was killing us.
Also, If I was McDermott, I would have never rotated Cook out. He was gashing us. I would have kept going with him but that is just me
