Patriots are actually playing for a lot here. If the patriots win they at least clinch themselves a first round bye. If the patriots win coupled with a broncos loss then they clinch the 1 overall seed. If the patriots lose and the bengals win then the bengals clinch the first round bye and 2 seed. If the patriots lose and bengals lose and the colts win then the colts clinch the 2 seed and first round bye. As you can see bear the patriots actually have a lot to play for. They definitely want the first round bye and home field for at least the divisional round.
