So I did go "mow the grass" and chill for a while, but it didn't change what I think.
It's the job of the OC, QB Coach, and the HC to come to a decision on who will be the starting QB, even when the competition is close. Playing all 3 is OK, even good to give them playing time against lower competition in non-conference games, but not when the real season starts.
None of the 3 have time to really establish some rhythm and get into the flow of the game. We are basically throwing away the first possession for each QB - so that's three possessions per game. And as Gundy said, it forces us to run a limited playbook. At some point you have to run the offense you will run in conference games, hopefully before the tough conference games start. We keep doing this and our offense will never get in sync.
Understand: naming a starter does not mean it has been carved in stone no matter the results. A change can be made if it doesn't work out. We wouldn't be the first team that began the season with a starter and later changed.
