I don't see the handles on film. He's projected as a small ball 5, who might be able to play as a stretch 4. Milsap had decent enough handles to be 4/3 sometimes playing more 3 than 4. If you're saying that he has that type of handle, he should be a lottery pick, because he would, in theory, be able to play 3, 4, and 5. I just don't see any world where dude can be a three. That's like Vlade saying Bags will play the three someday.
Milsap made a second team, all defense. Once in 2016. He was a good defender, but was mostly on ball, against 4s and 3s. More of the bully type. Liddell, if he translates, will operate as a QB of the defense type like Draymond, his help defense in particular, playing against 5s and 4s.
