Who cares that he left!!! If Gibson chose to go elsewhere, then I'd be bummed. Did the kid ever play a down!!?? Again, who cares!!!
Anyone who understands that having multiple talented QBs in the program pushing for the starting job, increasing competition at the position, making the eventual starting QB that much better. That's who would care IMO.
That being said, the kid wasn't working like he should've been, perhaps felt some sort of entitlement to the position, didn't want to be here.... don't let the screen door hit ya on the arse.....
