how do they go from just starting a football team to D1 in 4 years? There's schools winning titles in 1-AA that haven't moved up yet. anyone know the criteria from moving up? or down even.
The criteria have nothing to do with on-field success. Otherwise, Montana would have moved up many years ago, as would Appalachian State and Youngstown State.
Montana owned Boise State and Idaho when they were all in the Big Sky. Now Boise is one of the best teams in the nation, Idaho made a bowl last year, and Montana is still kicking butt in the FCS.
Here are the criteria, per the NCAA:
An institution classified in Football Bowl Subdivision shall meet all the Division I membership requirements set forth in NCAA Division I Bylaws 20.9.1 through 20.9.5 and in addition, shall:
1. Sponsor a minimum of 16 varsity intercollegiate sports, including football, based on the minimum sports sponsorship and scheduling requirements set forth in Bylaw 20.
Sponsorship shall include a minimum six sports involving all male teams or mixed teams (males and females), and a minimum of eight varsity intercollegiate teams involving all female teams. Institutions may use up to two emerging sports to satisfy the required eight varsity intercollegiate sports involving all female teams. [Bylaw 20.9.7.1]
2. Schedule and play at least 60 percent of its football contests against members of Football Bowl Subdivision. Institutions shall schedule and play at least five regular season home contests against Football Bowl Subdivision opponents. [Bylaw 20.9.7.2]
3. Average at least 15,000 in actual or paid attendance for all home football contests over a rolling two-year period. [Bylaw 20.9.7.3]
4. Provide an average of at least 90 percent of the permissible maximum number of overall football grants-in-aid per year over a rolling two-year period. [Bylaw 20.9.7.4-(a)]
