That says nothing of the odds of actually making a roster in year one, and says even less of sticking around the league long enough for those big paydays to set you up after retirement.
Basically, if you're playing the odds, the expected value of a college football scholarship isn't bolstered much by the professional payday. Nearly all the value is in that college degree (paid for by scholarship). So graduating with a degree that you can turn into a career is the best play BY FAR.
That takes us to graduation rates. These seem to be fudged a bit since, well, it's in the programs' interests to hide poor performance. You can do your own digging. Lots of articles about this, and it's not terribly great. The NCAA has their bookeeping, the football programs have theirs, and most expert agree that neither counts accurately. Best case, graduation rates are in line with general student graduation rates. Worst case, not even close.
The best argument I can see is that this is an outreach program for minority and under-privileged youth. The problem with that is the brain-damage that football causes.

College football programs are often very big profit centers. They typically pay for the other sports programs as well. That's why football coaches are paid the way they are.
College players should obviously be compensated in some manner as well. All that will do is reduce the profitability (or increase ticket prices a lot higher to offset, which may not be possible); it's unlikely to eliminate the business being quite profitable given the scale & ticket prices.
The instant example is a pretty good illustration---a crappy university president can do a lot more damage to a university than a crappy football coach (e.g. by making decisions that cause the failure of big chunks of the institution and massive financial losses), so judging the impact of hiring a better president vs a better football coach by whether they're responsible primarily for things with a plus sign or a minus sign on them in the accounting books seems... pointless?
(Plus, since the president is the football coach's boss, why would we account football revenue to the coach and not the president?)
For their math to work you have to assume that NONE of the donors who donate to sports would donate to anything else...I find that to be a fairly unlikely assumption.
That's incorrect. Most major football programs transfer a large percentage of their revenue above operating expenses, back to the university. Texas for example, which is typically one of the top five college football businesses (and nearly a pro level business), transfers about half of its revenue after expenses (ie profit) back to the university.
Look at the spending that the schools other than UM and MSU put towards athletics:

Most of the these football programs finance all sports for these large universities.
College coaches are paid well because the programs they lead tend to be profit centers for the school.
