1) I didn't criticize Booker. I merely pointed out your snarkiness for insinuating that he's clearly a good coach, ya know, because he's in the NFL. Even though his current position is entirely different than the one he had at ND.
2) A guy can be a bad coach in some respects, but good in others. There's a reason position coaches, coordinators, and head coaches get promoted, demoted, and reassigned all the time. Scott Booker coaching safeties in 2021 for the Titans does not mean he was necessarily a good ST or TE coach at ND.
