But there are still valid concerns:
Concern 1 - Coaches not being able to make a decision and trying to run a 2 QB system. It has been hashed out a million times, but they generally do not work. Coaches need to make a decision on who "the guy" is and stick with it even with both on the roster. Valid concern to have, I think our coaches could manage it, but it is a fair concern.
Concern 2 - playing Taysom hurts Tanner long term, and Tanner is most definitely the future. I agree, Tanner is not Jake. He isn't going to be rattled mentally sitting on the bench, but it's one more year he doesn't play (odds are he replaces and injured Taysom at some point, but not certain), one year he doesn't progress on the field, and possibly hurts his NFL future for a program that needs more guys going to the league. Once again - this is not definite, but it's fair.
