I have a completely new angle on the qb "controversy." Actually, this is a scenario that uniquely presents itself when you have multiple capable qb's.
Fast forward to the season, we have a capable starting qb, whomever it is. We have capable backups, whomever they are. When does CPJ use the hook?
You don't want to destroy a young guy's confidence and get in his head. All players need to feel they can make mistakes, or iow, can't play in fear of making mistakes. A young qb also needs to be able to work through a mistake in order to learn and get better. The only way to truly get better at anything is to make a mistake, figure it out, learn how to do it right. Real game lessons are the ones that matter most.
On the other hand, you don't want to leave a guy out there who is struggling mightily, for many reasons. He could suffer a huge set back in confidence and you risk losing the game and losing the support and confidence of the team.
So how much leash does the qb get? Does it vary depending on who it is?
