A few things:
#1 - the quarterback position is way different than most all other positions.
#2 - what ever happened to facing reality? i mean, Tristan Gebbia faced the reality that he might not get any meaningful playing time his entire football career, and he chose to do something about it and maximize his chances of being able to play football. I mean, if you knew there was virtually no chance of you ever getting promoted at your job as long as this one other guy was there, and there were tons of other companies who could offer you advancement opportunities, are you a poor sport to go work for another company?
If Tristan has potential to play at the next level, he should go where he can maximize that potential and his chances. If he doesn't, and all he has is four years for the rest of his life to have fun playing the sport he loves, then he should go where he gets the best chance to play as much of the sport he loves as possible.
