That's one way to look at it. Another is each have their glaring shortcomings and the staff is trying to figure out which shortcoming has the smallest chance of costing us a game.
We're nearing the 11th hour without a QB being able to really separate himself. Ideally it would've happened already at this stage. If one doesn't emerge in the next 6 days then I would take that as a pretty bad sign.
Martell had the cleanest scrimmage in terms of not committing a turnover but was sacked a half dozen times.
May God have mercy on our QB's soul this season.
