I spoke to the Student-Athletes at Erskine about 7 or 8 years ago and had a long talk with their AD (still there) about adding Football and the associated enrollment benefits of Football and other sports. He was ready to add Football that day if he could have. My memory may be a little fuzzy, but I believe he told me that, at the time, they were bringing in 30+ baseball players each year. Obviously, most of those were receiving very little to no scholarship assistance, but they wanted to play college baseball. They are currently showing 73 Team Members on their Baseball roster and Furman, by comparison, has 33. As he said, some of them play, some of them quit baseball and stay in school there, and some transfer. But they were (mostly) paying tuition while they were there. So, yeah, them adding Football is, most likely, highly "enrollment driven." As long as they are up-front about the numbers (# of Players in the Program, Tuition (and other ) Costs, and Available Financial Aid) with the Kids and their Families, then I don't really see anything wrong with it.
Plus, their "Flying Fleet" Team name/mascot is pretty darn cool.
Due West, SC...not so much.
