re: Myron Burton Jr has left the team

Okay then, I disagree with your "that good" statement. Myron could have improved incrementally during his redshirt year and the A day was the product of his efforts. Since that is possible, your assertion is invalid.
I can list many players that were "that good " but needed to redshirt because of depth and other similar reasons. If this is your main argument, I'd be more than happy to focus on this and not Myron.
