Actually, Mac got this wrong. TCU announced that the addition of the new luxury and premium seating on the East side will add somewhat over 2,500 seats, not "no more than 1,000," as Mac reported. It's still a small increase in overall seating capacity, but about 1.5 times larger than Mac allowed for.
Also, I don't agree with him that college football is going pro, or even semi-pro. College programs in general, even FBS programs, simply couldn't afford this. People who make this claim don't really understand the nature and scale of the huge economic differences between for-profit (NFL) and nonprofit (college).
Someone (or several) will undoubtedly try to correct me by pointing out that the NFL also enjoys the same nonprofit, tax-exempt status as college programs. If so, your information is partly outdated and completely wrong, for two reasons:
1. The NFL, a $10 billion-per-year enterprise, gave up it's nonprofit tax-exemption in 2015 because it had become so controversial it was (in the words of Roger Goodell) "a distraction."
2. Even when the NFL was still tax-exempt, the exemption applied only to the league's central office, not to the 32 local club franchises that are the NFL's primary money-makers. The local franchises have always paid full taxes on all income from ticket sales, television rights fees, merchandise sales, and sponsorships.
Could nonprofit college football possibly afford to go the same route? Not a chance. Among the 460 or so football programs in Division III, Division II, and the Football Championship Subdivision (FCS) level of Division I, every single program operates at a loss and is heavily subsidized by the host institution. These programs don't make enough money to pay their own operating costs, much less enjoy a profit.
Among the 130 or so schools in the Football Bowl Subdivision (FBS, or top tier) of college football, only about 20-25 programs earn even enough money to pay their own operating costs, much less a profit that helps pay for all the non-revenue-earning sports programs the institution operates for both men and women. TCU is is among the fortunate few that can afford this, but only very recently (last 2-3 years). Once those other programs are paid for, very little net remains to be added to the university's coffers.
Collegiate football is simply not designed to be a money-making enterprise. Under its current economic model, it will never go pro. It would financially fail overnight. But it does go to show that comparing nonprofit operations like college football to for-profit enterprises like the NFL is a completely inapt mismatch. Like trying to bake an apple pie using oranges.
