Charger, further to your comments:
(1) I think it was in the 1970's, the NCAA changed the rules to allow freshman eligibility. Before the rule change, freshmen couldn't play in varsity games. So, basically the NCAA acknowledged over 40 years ago that the acclimation period wasn't a big deal for new guys on campus. And there surely isn't a tougher transition for a new guy transferring from another college vs. a new guy right out of high school.
(2) The NCAA's priorities are to maximize profits for the universities, and promote fair play with respect to eligibility, recruiting, student athlete benefits, transfer rules, playoffs, etc. Maximizing profits is their first priority, fair play comes in second. Looking after the athletes' welfare is a distant third priority. The transfer eligibility rules were loosened because the athletes are gaining leverage against the NCAA, not because the NCAA WANTS to treat the athletes better. So, just keep in mind that the NCAA is representing the interests of university bureaucrats.
