Okay, I didn't explain it enough. Someone else can come in with an apathetic fan base, less alumni support and disinterested recruits and start from zero and build something new.
Someone else can do it, but I don't think the chance to do it and excite the fan base exists for anyone else. This is what everyone wanted, and if it doesn't work, some people are going to decide it won't work anymore, or it will work in a way that isn't the old way and they aren't interested. Winning fixes a lot of ills, but TO believed in "More Than Winning", and think that still matters to the fans.
