The $64k question is why Heupel went after Milton to start with, not why Milton was the choice coming out of camp. If we knew that, we'd know if this was a "not yet" vs "not ever" situation.
Also might have been as simple as we needed more depth and Milton was available. He might have felt that HB was just fine, we just needed another competent QB on the roster and he had no confidence in Maurer.
In the end, if we stand a chance of keeping
@VolsDoc81TX from offing himself when we end up 14-1 following a loss in the playoffs, we will probably need great play out of all of our QBs. I for one am thrilled that QB1, QB2, and QB3 are all much better than Rogue 2.
