You don't care what the stats say, yet posted stats to justify your post. There are stretches where he does what you say, but over the majority of his minutes he's doing what the coaches ask him to do, which is switch on the PnR on defense and set PnR and rim runs on offense. Which is why his stats look the way they do, but yes, please continue to watch with your eyes, because they are lying to you. You say he floats on offense, yet leads the team in ORB%, you say he floats on defense put leads the team in BLK%. I think you really don't have any idea what the coaching staff expects from him. He leads the team in FTr, by a large margin.
Texas has an elite two point defense, you don't have that without his rim protectio, which means other players need to rebound, mainly Kaluma.
So yes, he needs to shoot FTs better since he leads the team in attempts and gets fouled a shit ton, which is interesting for a guy that floats on offense, and he needs to stop shooting 3's because he sucks at them and it also means he's not drawing fouls in the paint.
