re: Bills should have held/tackled every receiver in the last 13 seconds.

Chip Kelly did this a few years ago against the Saints at the end of the first half. They've since put in a rule to stop anyone from doing this too egregiously, but I think it doesn't kick in until you've done it twice in a row, so it may have been workable here. I'm not going to criticize a team for not being flagrantly unsportsmanlike though.
