A lot of folks are going to want to wait and see what happens in the playoffs before declaring that Andy Dalton and the Bengals are done being the Bungles.

Certainly seems fair, given Cincinnati’s recent history: The team hasn’t won a postseason game since the 1990 season, when its current QB was 3 years old.

Still, give Dalton and his club this: After scoring the last 20 points to come back and beat the two-time reigning NFC champion Seattle Seahawks 27-24 in overtime Sunday, the Bengals (5-0) are gaining believers.

“We righted ourselves,” Cincinnati coach Marvin Lewis said, “and started putting one play on top of another.”

Dalton threw for two touchdowns and ran for another. He also got picked off once, though, and that big deficit against Seattle was telling. The big knock on Dalton is that he produces in the regular season — just not when it matters more. He is 0-4 in the playoffs, with one touchdown and six interceptions in those games.

There’s a long way to go until Dalton will need to confront those demons.

The Bengals are not the only NFL team with a perfect record so far that hasn’t put on perfect performances.

Atlanta is also 5-0, and also was pushed to overtime on Sunday, except not against Seattle but by a flawed Washington club, before winning 25-19. The Falcons are the first NFL team to open with five wins that include four after trailing in the 4th quarter.

Denver is a shaky 5-0, too — and that record is despite Peyton Manning, not because of him. He threw two picks Sunday, has more interceptions (seven) than touchdown tosses (six) through five games for the first time since his rookie season, and the Broncos’ offense failed to produce a touchdown for the second time in five games yet pulled out a 16-10 win at Oakland.
