Below is the excerpt from the article, for men's Div 1 BB, 15 in 2011 to 68 in 2011 and 108 in 2016. Looks to be an even larger rise in men's Div 1 FB.
The below also discusses which of the conferences do or don't place a restriction on grad transfers regardless of the ncaa's stated exemption but I find this part to be a little confusing or conflicting. I say this because it seems to suggest that the B10 and Pac-12 don't have the grad transfer exemption. However, I know there have been at least a couple cases with Michigan allowing or receiving intra-conference grad transfers. If true, that would suggest that the conferences and schools aren't willing to go through the process to enforce their stated restriction, either due to perception, media pressures, expected legal outcome, etc. In this regard, I'd say it's no different that the current Pitt-Cam situation.
Limitations on graduate transfers come at a time in which the number of them have increased significantly. Due to a litany of factors, including the opportunity to earn credit hours over the summer and getting the financial aid to do so, Division I athletes are graduating at a faster rate, as the NCAA’s graduation success rate in 2016 reached its highest point since the organization began tracking it. With a degree in hand and competitive eligibility remaining, some have turned to a rule that allows them to continue playing if they enroll in a graduate or second degree program. Under those same guidelines, they can transfer to another school without having to redshirt a season, as a traditional transfer does.
It’s an arrangement that has been beneficial both to players and the programs to which they flock. Not surprisingly, the popularity has grown. In 2011, according to an NCAA study, there were 15 Division I graduate transfers in men’s basketball and 17 in football. By 2015, those numbers jumped to 68 and 108, respectively. Last year, according to a list compiled by ESPN, there were 108 graduate transfers in Division I men’s basketball alone.
With no NCAA rule in place prohibiting the restriction of graduate transfer destinations, beyond permission-to-contact mandates, conferences and schools have enacted their own measures. From there, legislation varies.
The ACC exempts those with baccalaureate degrees from its intra-conference transfer rules, which require players not only to sit out a year, but lose a year of competitive eligibility. The Big Ten and Pac-12 have the same stipulations as the ACC, only without a graduate transfer exemption. Big 12 graduate transfers can move within the conference without penalty as long as they meet NCAA requirements. In the Big East, transferring within the conference in men’s and women’s basketball is forbidden, even for athletes who have graduated.
Beyond a conference’s guidelines, individual institutions can implement their own rules, a designation that has led Pitt and Johnson into their present stalemate. Pitt’s policy — which was applied to Johnson and Rozelle Nix, a 6-foot-11 center who transferred to South Alabama in May — was crafted by members of the athletic department, the faculty athletic representative and the office of general counsel and is subject to periodic audits from the university and the ACC.
