I like the Bengals to hang within a touchdown of the Steelers whether Ben Roethlisberger plays or not. I'm locking in now because the number will shrink if Roethlisberger is not cleared to play, which would mean Mason Rudolph under center and a far more conservative Pittsburgh game plan. 
Rudolph is a stiff and Roethlisberger wouldn't have the benefit of any practice this week. Cincinnati gives up a lot of yardage, but their scoring defense isn't that far below average ranking 20th giving up 26.8 points per game. 
Cincinnati has scored 27 or more points in five of its last seven games. Expectations were set high for Joe Burrow - and he's surpassed them. I don't expect Joe Mixon back yet, but he's only had one really good game. A hidden key for the Bengals has been the tremendous kicking of veteran journeyman Randy Bullock, who is 18-for-20 in field goals and perfect on 20 extra point kicks. 
Only once have the Bengals lost by more than five points this season. They are 11-3 ATS the last 14 times as a road underdog.
