San Diego is taken, but the Cleveland job remains open.
The other team that's available is the
Cleveland Brawlers. This team is a part of the 2011 expansion. The franchise has had difficulties finding their footing with just one postseason appearance. This team just needs the right GM to get off the ground.
If you are interested but the Cleveland job may be a bit too difficult, you can take the
Detroit Giants GM job. Its an original 16 team from the leagues inception with 16 postseason appearances and 3 championship titles with a solid core of young talent ready to start a dynasty.
