Seems to me that expecting Arch to contend for a Heisman or not have a learning curve after sitting the bench for two years (other than a couple of off schedule starts) is an over-reach.
Personally, I think he will be fine and grow week over week. Could be an 8-4 season, could be better and make the playoffs again. Glad he is a Longhorn, no hesitation in my optimism.
