I don't see this being close. The Bengals should have got blown out against the Titans, but you had Henry back after missing like 4 months and Tannehill was awful. But look at what that defense did to Joe Burrow. 9 sacks I believe. I see something similar here, and with Stafford under center, I don't see Rams scoring less than 24 points.
Bengals are good, but I just see too many hall of fame players on the Rams who are all in the prime of their careers. From top to bottom, the roster is better, and sure, that doesn't always result in wins, but this defense has been on absolute fire this year, and these past few games. They even held Brady to like 13 points in a superbowl loss.
Good luck with your bets fellas.
