Nice writeup, timvp.
The only thing that didn't resonate for me was the praise of Blair. To me, he looked a bit lost out there. His fouling was way out of control, he just didn't seem to be moving as quickly as everyone else so he got the fouls called due to awkwardness more than anything else.
On offense, he seemed pretty tentative running the plays. One time I remember Mason ran a pick and roll with him on the left side, and he sort of half rolled and left Mason in no man's land.
He was strong under the boards and on catch-and-shoot, no doubt. But I think he needs a bunch more game experience to become a good role player, much less a first-team player.
