My take:
For the first time in a long time, I thought we had a vastly superior gameplan, on both sides of the ball. Yes -- on defense as well.
The staff and players knew what OU as going to do (key on Bijan) and they picked out the players they wanted to target and had innovative plays designed to exploit those weaknesses.
The defensive scheme was designed for Spencer Rattler -- because they knew that Spencer Rattler is 10% points more accurate throwing on the run than in the pocket and he tends to hang the ball up. Which is exactly what he did. We dropped DLs into coverage, confused his reads, got turnovers. And they did such a good job that their reward is a QB who was oblivious to the circus environment and the scheme was not designed for him.
I did think that the TOP would be an issue for the defense, given the heat and the time getting battered by Brooks. And I agree that the LBs (especially the one who cannot shed blocks) require more coaching and I have to think you have people on the bench who can at least pursue at the point of attack.
Finally, that was a different Texas team than I have seen (exception 2018) since 2008/9 -- tough, hungry, ready to fight. So much better prepared than battering Sam and hoping he can will you to points.
That was a brutal loss -- one I will remember forever. But I like this staff and people calling for coaches jobs -- that is part of the problem -- always changing coaches, no continuity, panic in the House of the Burnt Orange. Since Bob Stoops showed up, we are only winning 1/3 of the Texas/OU games -- and part of it are whiners on the board with knee-jerk reactions, rolling up into the staff and to the AD so they do not lose tickets. No continuity for Texas, same system for OU.
