For me to start a guy at QB who had less experience (or none), he would have to be performing CLEARLY better in practice and scrimmages and I can't emphasize the word "clearly" enough. If there are marginal differences, then I think you have to go with maturity and experience every single time. The reasons for this are many. First of all, every single player out there is putting in a ton of work. There is a lot of sacrifice in this sport. Those of them who have waited their turn, or maybe even have been starting, deserve to be rewarded for their time and efforts if there is negligible difference between competitors. The younger guys will get their turn. There is an eligibility limit. You will lose a team faster than anything if you push young guys ahead without having made them clearly prove it. Having said that, everybody wants to win, first and foremost. If a younger kid is killing it, everyone will know. Players aren't stupid. They know who is making plays, who is hard to tackle, who they can't catch, who puts the ball on the money, who makes the best reads, who hangs on to the ball, who jukes them out of their shoes, who hits the hardest, who they can't keep out of the EZ on short and goal practice. My experience tells me that teams will rally around the younger kid when these things are self evident. My message to any young player would be "if you want to play, then it is your job to make it impossible to keep you off the field, otherwise take a seat and watch and learn."
TECH fans don't have to look too far in the past to see a case where this was handled poorly. Donnie Davis was a QB who had talent and had been in the system a little while and was developing. The coach never to be named started a brand new kid, who, by all accounts, wasn't killing it in comparison and the rest is history. That was a fractured team because of it.
If we are in the situation where a young gun has separated himself, then great for us. Nobody will be happier than me. 4 years of consistency is a beautiful thing for any program. I just have no clue as to what is actually happening right now. It is no secret that I have mentioned a current QB that I think will rise to the top eventually and make it impossible to keep him off the field. However, you won't hear me calling for him to start right now, nor predicting such, because I can't see how he is progressing. Every kid is different. The truth is, I have no idea how the whole competition is going at all between any of them. It is a little unsettling but exciting at the same time.
Who should start? Imagine you are in enemy territory, moving through the jungle, leading a recon mission in a small unit. Everybody's life is on the line and mission is critically important. Who are you going to put on "point"in your formation, the guy who shot 10 points better on the range last week, or the guy who has done it before successfully? Just saying. Football isn't life and death, but you may not want to suggest that to a CFB fan from the south.
