That's very true. However, his point is that the odds of pro status are very slim and these guys should be paid now, especially since coaches are averaging 3.7m. How would you react if your company told you your pay was meager because you were supporting people in other departments who didn't generate any revenue? It's hard to wrap your head around players being paid, but things have changed drastically. In 1981 Bo Shembechler made 100k at Michigan. With 3.5% inflation that number would be 385k today. Harbaugh makes 9m. That's all you need to know.
Personally, it's not all I need to know. While I agree hundreds of college basketball and football coaches are wildly overpaid, it doesn't just end there. Plenty of schools have highly paid golf coaches, or track coaches too. The issue isn't the need to pay players - not in my opinion anyway. The issue is the megabucks being paid to coaches, ADs, and universities for TV deals, and other things such as apparel sales. Somewhere, for me, there's a middle ground that makes sense, and for me it would start with allowing players to make money on their likeness. To me, the minute we start seeing players "paid" as you and others suggest, is the minute we start seeing the end of college sports as we know it now.
Another simple solution is this: take all the money made by TV rights fees, and distribute it equally across every school in the NCAA. Then, the have's and have not's aren't separated by the same enormous chasm, and the have's can't afford to pay football coaches some of the insane salaries they get paid. Of course nothing like this would ever happen in the NCAA, I know that.
