Hardly. He was the #1 overall recruit in the 2022 class and committed to Texas, decommitted after Tom Hermann drove Texas off a cliff that season, reclassed to 2021 to capitalize on NIL, made like 1.5 mill in NIL money to go to OSU for one year, and was only at OSU for his true freshman season. CJ Stroud, who was the class before him, won the starting job in Ewers' true freshman year so Ewers went back to Texas to play for the new coach, QB whisperer Sark. He was the most sought after transfer in the portal for the short time he was in it, during which it was a foregone conmclusion that he would go back home to Texas. .
The rest of the guys on your QB list were essentially Day 1 starters at their schools, established high level starters when they transferred, and transferred due to coaching/schematic changes and/or to improve their NFL draft potential and/or to play for better programs and/or to make more NIL money.
