You answered your own question...the school will just say they accept the student and they are eligible. They will just bend their standards like they always do to make it work.as far as I know, the individual schools still have the right to determine eligibility. as long as the players are still considered student-athletes, then the players have to meet academic criteria to become eligible and remain eligible.
ergo, it would be very difficult if not impossible for a player to transfer midway through a season and immediately become academically eligible at the new school.
I get it. all the changes are difficult to cope with, and it seems like anarchy. but there are still some rules and some structure in major college sports. it's not total chaos, yet.
times change. rules change. when I was in High School, Freshmen were ineligible to play Varsity sports in college. Lew Alcindor (later Kareen Abdul-Jabbar) had to sit out his FR year at UCLA. Oh - dunking was also illegal in college hoops at the time. those rules changed. life went on.
here are some quotes from 1972 when FR were allowed to play college football and basketball:
When asked about the rule change, Rutgers football coach John Bateman told the media, “If freshmen can play, you don't have a very good program.” Chuck Neinas, commissioner of the Big Eight Conference (which eventually became the Big 12 Conference), said, “Our football coaches are unanimously against freshman on varsity teams."
Missouri athletic director Sparky Stalcup told the Kansas City Star that freshmen eligibility in basketball and football would be "a whole new ballgame."
"If the other major conferences do it, we'll have to." he said. "It's a recruiting gimmick."
This is not the same as the Frosh Rule change so your quotes are rather irrelevant.
