Unless you just want a barebones team with zero financial support (think KSU football in 1980s), you are going to have to spend a lot of cash to start and operate a new program. Don'tget me wrong, I'm in favor of adding softball and both men's and women's soccer, but at least I acknowledge it would be expensive to do.
