I speculate Quinn Ewers is facing true adversity for the first time in his life. I relate, I had always had school come to me pretty easily- until law school, where there was a curve and I got my rear kicked. I rallied, but it took a whole lot of introspection and finding discipline I had never needed before that point. How Ewers deals with innate talent not being everything it takes at this level to succeed will decide his future. If not, Hello Arch (not a bad backup plan).
I think Ketch has written in the past the college team with the most experience QB has a huge advantage. See TCU this year with Max Duggan. Seriously, given we had a first-year starter at QB and played a lot of true freshman on the OL, the knocks we took this year were inevitable. 8-4 was my season prediction, and we hit it. The trend is is distinctly upward, and we are built more soundly on the OL and DL than we have been since Mack Brown. The foundation is in place.
If Ewers is better next year- then we're cooking with grease- if we have have to deal with another 1st-year starter at QB- it will be a little tougher, but our OL will be much better for a first-year QB starter and our young RBs.
Grind Quinn Ewers, grind. Be mentally resilient and take your humblng and use it to get better. Do the gameplan book work, watch all the film, and focus on the QB mechanics details. If you do, greatness can be yours.
