Some thoughts:
My biggest gripe with Tatum's game is that he doesn't make decisions quickly. He gets the ball, faces up, jabs, takes a bounce or two, and NOW he's ready to make a move. This does the defense a lot of favors, and the quicker the Celtics coaches erase all of the extra crap, the better. Aside from that, he's a natural scorer and he's not the liability on defense that some claimed in the days leading up to the draft. Looking forward to watching him play in real games.
Fultz left me with a few questions. We know his handle is very nice, and we know he can shoot. Can he finish in the paint over/around/through length? Can he make his free throws? Is he willing to learn how to play defense? No question that he'll be good though.
Jaylen Brown had it going last night. Need to see better decision-making when passing the ball. I appreciate that he was trying to keep his teammates involved, but making stupid passes to the other team is not the way. He's an athletic freak though.
I want to see more from Ojeleye. His shot looks good, but he'll need to make a lot of progress on defense before he earns minutes.
Not sure what a lot of you were expecting with Zizic. He looked exactly how I expected him to look before he gassed out. Active, runs the floor, good on the glass, but he's ground-bound and not especially quick. Need to see him improve his conditioning - getting visibly exhausted in 19 minutes is pretty bad even for Summer League. I think he can help us in time, but expecting him to come in and be our starting center is wishful thinking. Probably a situational guy at best in his first year.
Not especially interested in anybody else.
