I agree with @ELLIASJWILLIAMS , just name a starter already and give them the reps. There is no way that a couple of days of competitive practice are going to give you anything more definitive than the body of work both QB’s have already shown to the offensive coaching staff.
What if that body of work isn't convincing enough? If both QBs do a comparable job? I mean, you need to give them both enough reps to make a decision if it's pretty close between the two.
And fwiw, I don't know. Have no idea what thr coaches think about it. They may already know and it's just a ruse, they may already be giving one the most reps and the other guy gets more reps next week. I don't think it matters that much anyway. This is more a dress rehearsal for those who will still be around next season.
