The competition: There are 10 teams in the IFL, which was created in 2008 by a merger of the Intense Football League and United Indoor Football. Based mostly in the upper Midwest, it's essentially the minor leagues of indoor football, with the six-team Arena Football League considered the top level. Believe it or not, the IFL has a rival (they've taken each other to court) in the eight-team Champions Indoor Football. The IFL has never been the picture of stability. There are 50 franchises that have either jumped to another league, folded or failed to launch.
