I think it had less to do with A&M and more to do with Quinn Ewers. We moved to Austin, temporarily, last month and you hear constant chatter about Quinn Ewers. He was their Trevor Lawrence. A&M is almost in the periphery here. It's more about UT and Oklahoma (who have a constant string of All American QBs).
Yep, should have included Oklahoma in this as well.
My brother got his Ph.D. from A&M and my sister in law is a UT grad and the they lived in Houston for 20 years. Like you, I've heard plenty of Texans talking football. To them, losing players to rival schools, is, well, they should invent a new word for how it's viewed. Failure is not strong enough.
In any event, they now have a guy who's worked with some top college QB's so the expectations will certainly be high on that front.
