For Max money? with this roster as currently constituted:
20+ pts per game on 45+% FG, 78+% FT, 30+% on 3's. Becomes a shooting threat where defenders no longer back off him
10+assts per game
5+Reb per game
C's 7+ seed in playoffs
Raises everyone's play on the team to another level when he's on the court.
in the MVP discussion even without playing on a top team.
For the record, I don't think he'll achieve any of these things other than the assists and rebounds. I think his shooting % will rise across the board to the point where most people will acknowledge he's demonstrably better and teams can no longer automatically sag off him from the outside. he won't hit those % though. he'd also have to be superhuman to get this roster into the playoffs which is what it would take for him to be in MVP discussions.
I don't consider him a 'Max Contract' player but I do think he's worth more than he's currently making -- even before the current rash of foolish contracts being thrown at lesser players. Personally, I think $16 mill per year starting off is fair. would consider as high as $17 mill but over that is overpaying.
