I think the Bengals "should" win and will expect as much. I'm with Army in that the most promising factor might be that the Titans offense is so ripe for exploitation. Tannehill has been worse than ever so far this season, and I think the defense can prevent Henry from just devouring the game (at the least, he hasn't done so in any of the last three matchups).
Frankly the two teams are nearly clones so far. Burrow needs to take another step forward. Otherwise it's liable to be a 10-9 kind of game.
