It kinda goes back to that Oklahoma/Georgia lawsuit in 1984 regarding television rights. When the NCAA was removed from the equation, the proverbial "powers that be" were given a tremendous leg up in their quest to remain in those positions, and upward mobility became excruciatingly difficult for everyone else. If "we ever see a crap team come out of the bottom and win nattys," I'm assuming it'll be a P5 team with a less respectable history than its other conference counterparts (Maryland, Duke, Baylor, Vanderbilt, Wazzu, etc). But a G5 school? Fucking forget it. The only success you'll see out of that will be from the already established powers a la Boise State. The rest will suffer as they must.
There's a really good read by Sally Jenkins that she wrote about 10 years ago in which she covered its effects:
"But [SCOTUS Justice Byron] White’s dissent is great reading anyway, because it’s so clearly anticipatory. If the NCAA was a monopoly, he also saw it as a bulwark against today’s ruthless, distrustful dealings. . .
Listen to the arguments of the Oklahomas and Georgias now, and indeed you can hear the unmistakable ring of the cash register. Fred Davison, Georgia’s president at the time of the court case, didn’t bother to disguise his real interest. He sought an end to “a tyranny of the majority to impose itself on the commercial enterprise” of a handful of big-time football schools.
What really drove Oklahoma and Georgia crazy was that small schools received more in rights fees than they would in a free market, while the football powers received less. They had to share spoils with nearly a thousand schools that made up the NCAA majority. The Hofstras got a cut of Oklahoma’s TV checks.
But, White asked, so what? It was a small price to pay, he suggested, for holding off rampant commercialism at the door. Profit- and load-sharing was “an essential aspect of maintaining some balance of strength among competing colleges and of minimizing the tendency to professionalism in the dominant schools.”
We can debate whether or not the SCOTUS decision was the "right" one or not, but what's beyond debatable were all of its effects on the competitive balance between the schools.
