No one answered your question. All they had to do was run up the middle, run the clock down to 2 seconds, and kick
A walk off FG. Make it and win or go to OT.
Instead, inexplicably they threw the ball, Stroud and the TE were not on the same page, it was ruled grounding, they lost like ~7 yards, the clock stopped, and they had to punt. They went from worst case going to OT to giving the ball back to Buffalo. Their punter had a great punt though.
