Score TD's instead of FG's. Block on the QB sweep, don't go for 4th and 27. Dont run with Gore at the end of the half for 2 yards. Dont hold the ball recklessly and fumble. Dont try some ridiculous lateral. Stop them from scoring 19 points in the second half. The Bills could have won this handily if they had killer instinct. The kickoff thing is pretty weird and I dont see why they did not keep it a TD, that flips the game more than likely right there.
If the Bills had won, the Texans fans would find endless crap to complain about too. Ford held Watt pretty good for instance, never called.
