the obvious pick is the Texans however keep in mind they are travelling west 2 time zones to play a late game. this is a major disadvantage for the road team and their bodies could run out of gas in the 2nd half from it.. their bodies think the game is 9:30 and not 7:30 local time.
i would take SD in a heartbeat for size but they really have very little talent so its hard to think they don't throw the game away based on just that
