Seems that this would be a more reasonable model for CSU - $120 million, 40k, expandable if necessary. Doesn't look to shabby either. UH has a very similar revenue stream to CSU as well - ticket sales + donor contributions total $8 million per year at both schools, according to USA Today.
UofH is making themselves as attractive as possible for the next dance. We'll see if it pays off, but I think they are going about it the right way and they have the added benefit of being in a large tv market and a fertile recruiting ground. I like their chances in the next round of moves.
