While I never like to agree with Gunther, I think he has a point. In the limited reps I saw all the QBs it did seem to be 1. Huntley 2a Shelley 2b Tuttle. I think Tuttle was only 2b for redshirt reasons.
That being said I believe their is more to this whole story other than Tuttle is p**sed he wasn’t the first backup.
