I'm sure guys like Urban Meyer and Nick Saban wouldn't like it. They routinely run guys off who don't cut the mustard. Not to mention when a new coach comes in and does the same thing to get his guys in place.
In my day there was an unwritten rule that if you kept your nose clean and went to class, they kept you around, even if you had a career ending injury or didn't pan out.
It's not a kids fault if they made a mistake on talent.
