Belldozer, great post.
First, I'm think it is nonsense to say OU "is getting what it deserves" by bringing in transfer QBs that became great ones at OU. Like you stated, none of the three were starters and were not considered huge losses. This kind of BS seems like UT stuff......and we know how well Texas recruits in-state quarterbacks.
Before the 2021 season, I was not in agreement with the (usual) preseason hype about OU. The team had lost 4 of its best defenders, including DE Perkins who immediately improved the defense and then RB Rhamondre Stepenson who did the same for the offense. Both arrived back from suspension at midseason. Plus, there were losses on the offensive line (Humphrey, Ealy), Stogner's injury which he has yet to fully recover from, Calcatera's transfer, dismissals of Henderson and McGowan and even Tre Norwood who could make big plays in the secondary.
I saw the worst ten-win team ever with no improvement from game one: no quality wins and losses to the only teams of equal or better talent. And the win over a decimated Oregon team was no big deal.
All that aside, I predict a 2022 OU team that will play inspired football.....and IMPROVE as the season progresses......a Jekyl and Hyde transformation.....even with a bump or two along the way.
