I agree with this...to a certain extent. However, I still believe in the "if you start something, finish it" work ethic. For whatever reason, this young man isn't quitting on the fans, or his boss (the coaches). He's quitting on his teammates. He spent all spring and summer training with these guys, and with the new coaches. The time to quit would have been earlier, before the line was drilled based on the expectation that he would be in that position.
He's not injured, so (to me) the only thing that would make it okay for him to dump on his teammates like that would be a family emergency. I understand that having someone that doesn't want to be there can be dangerous. I'm just saying that (barring extenuating circumstances) he should have made this decision earlier.
