The Bengals have beaten the Jets, Dolphins (in a game Tua got knocked out of) Saints, Falcons, Panthers, Steelers, Titans, Chiefs, Browns, Buccaneers (had to come back from 17 down) Patriots (almost blew a 22 point lead)
Their losses
The Steelers week 1
The Cowboys week 2
The Ravens week 5
The Browns (without Chase) week 8
The Chiefs win was impressive but outside of that, they have beaten some bad teams with a 17 point come back against one and almost blowing a 22 point lead to another.
They have 4 losses, two of which were against bad teams (one without Chase) the other 2 were against the Cowboys and Ravens which are playoff teams.
I'm not saying that the Bengals are bad. They are a very good football team with a great QB and a lot of explosive players, but outside of the Chiefs, they haven't really beaten anyone noteworthy and have lost games they should have won. It's going to be a very hard fought game Monday night. But just something to point out
