It's been years since I've heard any complaints about how the NCAA does their calculations. Those calculations were once very much in question. It basically gives you credit if your athletes are graduating, or are on schedule to graduate (if they are leaving or transferring). It doesn't matter if you have 4 year players or not. If you're only graduating 50%, or only 50% are on course to graduate, there's a problem,
I looked at Xavier and they are anywhere between about 90 to 100%. They have always advertised that they graduate 100%, but that was obviously a lie.
