There were no best players in that Cavs series. We got destroyed on the boards by Thompson and Mosgov.
12/7 on good efficiency in really limited minutes(he missed the whole stretch run with a back injury) is good.
Accept it.
When your team is totally outclassed, you can throw all the numbers out the window. It's like thinking a 20 pt a game scorer on the worst team in the league is actually a real 20 pt a game scorer. Chances are he's not.
Going by the eye test Thompson/Mozgov's dominance on the boards gave them zero chance of competing. Sully was one of the guys getting dominated. On top of that they needed him to step up vs Atlanta last year and he was a no show the entire series.
That's why he's no longer a member of the team - though I am advocating bringing him back if Bogut's not a possibility. He has one skill that can help - against certain players - if he feels like playing which I'm guessing (hoping) he will. He also improved his defense quite a bit during the regular season last year so that likely wouldn't suffer by giving him minutes.
