I think it was a combination of good coverage by the Bills secondary and some blocking mistakes.

A: Cal, I disagree. On the sack on the Dolphins’ first offensive play of the fourth quarter, right tackle Vernon Carey was beaten badly. On the one in the second quarter from the Bills’ 33, Ricky Williams failed to pick up the blitz. On the final sack of the day, you might have a point, but the Dolphins were clinging to a 13-10 lead with a little over two minutes left at the Bills’ 43 and were just looking to avoid the big mistake.
