I think he has a point if you're only considering the long term. If you put a serious commitment into the program, in the long term you'll start winning more, ticket demand will go up, and you'll expand your stadium to meet demand. The reason why the Gophers only had to build a 50,000 seat stadium is because the commitment hadn't been there for years and it showed on the field and in ticket sales. However, this ignores the short term re-commitment we've made to our football program, which will take time to affect performance and ticket demand (and therefore stadium size).
