Per 36 minutes sully is
11 points / 11 rebounds / 1 block / 1 turnover
Al Jefferson rookie year
16 points / 11 rebounds / 2 blocks / 2 turnovers
Kevin love rookie year
16 points / 13 rebounds / 1 block / 2 turnovers
Elton brand rookie year
19 points / 10 rebounds / 2 blocks / 3 turnovers
If sully's minutes keep increasing and he can get his numbers per 36 up to about 16/13 and keep the silly fouls down that'll be a great rookie season.
What is worth mentioning regarding those comparisons is that Sullinger is actually playing on a better team and has a much lower usage rate. They are not running a single play for him unlike those other players who were getting touches on the offensive side which of course improved their scoring rates.
Of course there is the fouling issue to discuss. I think it is a combo of three things: One, Sullinger plays basketball like it is 1985. He is a banging, rough and tumble type which until his rep improves will get him quick whistles in this new ticky-tack foul league. Second, earlier his rotations were a bit slow. Now that he grasps the defense he is "getting it" and is rotating outstandingly. Subsequently his post D is second only to KG and his fouls are starting to drop. Third, he knows he is not playing starter minutes so he knows as a bench guy with muscle that he occasionally has to deliver the hard foul down low. In my mind that is just wonderful.
I think he can give you 20 and 12. The rebounding we see already. Regarding the scoring: He showed effective three point range in college along with excellent mid range touch, he has great technique and form on his jumper. With all the pick and pop the NBA runs along with better spacing he will drain jumpers once given the green light. Additionally he is improving down low. His ability to create space and use angles will help him in the post. Finally, he will soon draw fouls, not get whistled for them. He has a great free throw percentage and if he can get 6 to 8 of those a game you are looking at 20 point scorer.
Not bad for the 21st pick in the draft.
