Jet fans are now Cowboy fans. The Cowboys have a lot of talent and when they put it together are a nasty team. If the Cowboys can beat Pitt and Cinci one of those teams is guaranteed a best case 9-7 record since they play head to head.
Jet fans are also Pat fans this week. Beating the Texans would put them 1 back of the #1 seed and home field. The Texans won't want that to happen thus they will have to plat out their schedule. Also you don't want the Colts beating you if you might face them in the playoffs. You don't want to give them any extra confidence that they can come into your house and take you out.
