11th and 12th this season, while Nürnberg was nearly relegated last season. Not sure they belong in this list.
Bochum, Kiel and Fürth finished 8th, 11th and 9th last season.
The year before that Bielfeld ran away with it after finishing 7th in their last season.
The year before that Union got promoted after they previously finished 8th and Paderborn just went straight from 3rd to 1st division.
The year before that Düsseldorf and Nürnberg finished first and second after finishing 11th and 12th the year before, while Kiel, being newly promoted, made the playoff.
It's the gimmick of the 2nd division that there are always one or two different sides who have a great season out of "nowhere". And it's why all those clubs who "have" to earn promotion are so fecked now. Because there are like 3-5 legitimately big clubs who everyone expects to duke it out and then there will be another one or two surprise clubs, who have built into their one great season for a couple of years.
