Winning % - The Bengals are 25th. Better than the Saints, Jets, Texans, Jags, Falcons, Cards and Bucs.
Post Season Winning % - The Bengals are the worst.
Last Post Season Appearance - 2015, tied with Cards, Broncos, Redskins and better than 49ers, Jets, Bucs, Browns
0 Super Bowl Championships tied with several other teams
2 Super Bowl appearances - tied with Panthers, Chiefs, Falcons, Ravens, Bears. Better than (1 appearance) Saints, Cards, Titans/Oilers, Bucs, Chargers, Jets and (0 appearances) Lions, Texans, Browns and Jags
I would rank them ahead of the Browns, Jets and Lions. And similar to the Saints, Cardinals, Buccaneers.
But Mike Brown is the worst owner in history and anything they have won since he has been in charge is in spite of him and not because of him.
