Bengals are no joke. I loved what I saw of Burrow last year before his injury. It seemed like he threw for a gazillion yards but just kept coming up short. Now they have a stacked defense and more weapons on offense.
It's not crazy to think that the Bengals could win that division, especially with Mayfield banged up and the Ravens being wildly inconsistent (needing an NFL record FG to beat DET, then blowing out the Chargers, before getting blown out at home to the Bengals).
Chiefs seem to rely on the home run ball, which has worked for years. But when that doesn't materialize, they just fall apart. Even their SB win was like that: nothing all game, then FINALLY they hit the long ball miracle play in the 4th quarter on (I think) 4th down.
This year those plays are not happening, and their defense is horrible.
