South Alabama has fewer students and is in a small city than UAB... yet they think they can do better in terms of attendance. The only thing playing in their favor here is that they don't have Alabama playing 50 miles away from them. But they'll still face competition from Southern Miss, Troy, and Auburn... LSU and Florida State are just several hours away as well.
The thing is... even out of the 16,000 or so students that they have, they got about 2,500 students to sign a petition saying they wanted football. So they'll be raising student service fees by $300 per semester (based on what I was reading) and they base this whole move to add football and raise those fees on the wishes of about 15% of the students enrolled there.
