I said this last season that I can see him playing 20 - 25 mpg in 2010-11 with improved scoring. I can envision something like 10-12 ppg and 6-7 rpg if he averages close to 25 mpg.
I think at 20-25 mpg that he will still be a net positive on the court in 2010-11.
I don't know if he is ready to handle 30+ mpg on a regular basis. I think he needs to score more before he starts to get some breaks on the calls by the officials. He still needs to learn how to not commit so many dumb fouls and better position himself as well as continue to improve his footwork on both offense and defense. He needs to learn how to successfully take a charge. Hopefully Carlesimo can help him with his defense like English has and continues to do with his offense.
Can he start and only average 25 mpg? I think it would be difficult.
I think for him to average anything over 25 mpg at this point would require him to reduce his effectiveness on defense and the offensive glass unless he can make some significant strides in reducing his fouls without comprising his effectiveness on defense.
Could he be effective at this point playing 30+ a game. If and when I see it happen then I will comment on that
