I think you'd pretty much have to be an NBA player to even be able to focus enough to really learn anything. In my youth I was a professional musician, and early in my career I attended a masterclass from a very famous shredding style guitarist called Steve Vai, it it was like 2 different crowds of people together in the same room. There was the very accomplished/technically proficient players who were hyper focused and learning and then there was the fans who most stood staring in awe. I feel like if I was lucky enough to receive 1 on 1 coaching from Dream (or Harden and a few others in fact) I'd struggle not to just stand there trying to not look stupid and blurt out "can I see the dream shake up close?" haha.
