My two working theories:
1. As shoot the three said, Ben isn't going to play kids that can't defend or bring consistent effort. Based on everything we've heard, Trey Thompson isn't passing the defense test. Brendan Hausen had the same issue last year and never played despite the NIL commitment and success at KSU. Unless Thompson gets his shit together on defense or we get really desperate on offense, he may ride the bench all year and then transfer out. I don't think Ben gives a shit that he was a 4 star recruit. I'd prefer he get a chance, but hard to get too upset at Ben for being a defense absolutist after Fran.
2. Ben has always been clear about liking Peyton's defense, which has been based on practice and, I assume, high school/AAU. Neither of which exposed him to athletic guards like Virginia Tech. So perhaps some limitations were exposed on Tuesday. At his press availability later in the week, he said the tape showed the big were terrible in pick and roll and leaving the guards exposed. So who knows. But over time, Ben's not going to get away with playing Peyton for defense and Peyton not providing that defense.
