This is a poor screen shot, but here's a look at a typical defensive breakdown.
The ball is on the O. AA is already trailing the play because he was playing way too soft when just one pass away.
Kalib's man is about to set a screen--Kalib does nothing but stand there. He has no idea Avery's man (Pack)is cutting behind him, so he doesn't get a body on him, but allows him to flash all the way across the court without having to adjust his path.
Avery goes over the screen, is way late, doesn't close out, and then just flies at the shooter. No, he didn't touch him, but still that was a four point play that didn't have to be that easy.
I don't see evidence that these kinds of plays are getting corrected by the coaching staff. I'm not in the film sessions, maybe I'm wrong.
If this happened at Texas Tech, a sub would already be on his way to the scorers table for either or both of them.
