If I were the NCAA I would spend time on actual health of the student athletes and maintaining competitive balance among the titans of the sport. The smaller rosters were imposed by a court case and they seem to be creating the conditions for the latter. So, really nothing they did.
College football and basketball are both very popular. They generate revenue for a lot of people. That runs from the ad exec who somehow sells Liberty Mutual the dross they put out as commercials to the bar that shows a mid-week basketball game between a couple mid-major schools to give the barflies something to look at as they drown their sorrows. College sports also make a lot of money for the gambling element. I wonder what more could be done to ensure these sports are not manipulated by self-interested people in these large organizations.
