Ya know, Quinn Ewers looks every bit the player that Arch has and I don't see him as simply bowing out. Georgia has some highly thought of quarterbacks as well. Personally, I don't see this as a decision based on a guarantee to start.
One thing I do believe is he'll have more control of what happens at Texas than UGA or Bama. The "powers that be" still have a lot of weight in decisions made in footballāon and off the field. I can see the Manning's with similar influence.
