Should I transfer from the school I love to start at quarterback?

You are both freshmen. I would give it at least a year, possibly two, before making a decision. And, right now, you say you are the starter. Go to some quarterback camps and work on your mechanics. You have time to continue to develop. Take a deep breath, remember that everyone loves the backup, and concentrate on improving your skills. And, remember that competition with him will make you better if you do decide to transfer for your junior or senior season....
