1. Houston Texans
This one feels obvious. And though some will make the argument that there's a kind of unspoken bond between division rivals once the postseason starts, I'd say take a lesson from the Falcons and Saints. Maybe I'm misreading the room, but I can't imagine Falcons fans rallying behind the Saints in a big Divisional Round game, or vice-versa. Rivalries are more fun when even meaningless football creates controversy. And if the Texans made a serious run, there's a nonzero chance that the Titans would have to stand there on the sidelines next year, opening Thursday night, watching Houston raise a banner. Can't have it.
