ScoobyDoo in another thread asked me to benchmark Sully's rookie season against other recent players. I hunted around and it looks like these are the guys who posted seasons that were pretty similar in terms of per-36 averages. (Sully had, roughly, 11/11 with 1bpg and 1spg.)
Greg Monroe
Al Horford
Ed Davis
Nik Vucevic
Ty Thomas
Sean Williams
Enes Kanter
Mike Sweetney
Andris Biedrins
Thomas Robinson
This seems pretty encouraging to me. If Sully is healthy, the higher end of this range includes some very good players. Of course some guys have flamed out, but in Williams' and Sweetney's case I think you could say it was more mental than physical. Everyone else on the list ranges from legit NBA bench player to possible future star. (I think it's to early to tell with T-Rob, so I'm not including him in that statement).
