This third-game/redshirting thing is a concern to me, as well.
I will say for myself...college football is the only sport I really follow. I've never particularly cared for the NFL, largely because of how quickly the players move from one team to another (same for MLB, etc.) And well...here we are.
I thought the policy used to be “5 years to play 4”, and that six-year seniors were only medical redshirts.
Considering the sport is nominally tied to education, it would be good if we reverted to that rule.
Quitting three games in really sucks. I hope he’s enjoying his single UNLV online class.
