Agree with the last few posts; he looked great for his first night back... or really any night, actually.
His shot looked smooth, he gave some effort on defense, and his moment with Mike Brown was actually nice to see, especially for a Brown hater like me. I don't know how much stock to put into it, but speaking of heartwarming moments, I really loved the moment he and Kyrie had (I think in the third quarter) near the scorers table where Kyrie was seemingly trying to pick him up and looked to be offering some genuine encouragement. Hard to tell, though, given I obviously don't know a single thing that was said.
If I remember correctly, that came right after a no-call on a Dion drive where he went strong at the Spurs big in the paint (Splitter, I think) and it probably should've been a foul because of body contact (that's a foul if it's Wade). Believe it or not, Dion yelled "aye" as it happened and threw up his hands and didn't get back on D.
That play was a great example of two things: 1) in general, I see him going inside with strength instead of just finesse more often recently, which I think has been one of his biggest problems in terms of finishing inside, and that's encouraging; and 2) echoing pretty much everybody here, he basically needs to start building up goodwill/humility equity with the refs by absolutely forcing himself to keep his mouth shut after every single drive, foul or not, and intentionally break his habit of yelling and putting on a display. It should be a conscious intention on his part to just do it - not because big boys don't cry, but more because if he does that for a while, I think the refs will start to take notice. Maybe later in his career he can re-adopt "aye" into his on court vocabulary, but I can't see such a drastic 180 for him going unnoticed and unappreciated by the refs. The refs see all.
