For the No1 pick,Brown is a bust period.   Big but not so strong body, fast and quick but not smart enough to use it, good leaper without motivation.  All that plus butter finger that can not catch creampuff.

 Bynum has received limited playing time is doing well.  He was getting @ 23.5 min but almost getting pt/reb/blk. 10/10/1.5 avg.

That is not so bad for someone who started to play basketball at 15 years of age in 10 th grade (高一)he now has total 6 years of basketball experience. 

I think given the playing time and maturity he will be a 20/10/2.5 player.   that will put him in the same class  with the NBA elites.

As for John's concern, of other young center emerge when A Train gets good...  keep in mind he is 20 now,that is not exactly that old (college Junior) and there are 30 NBA   teams how many teams will have quality center that can provide 20/10?

I think Brown will be mid range garbage player in 2 years, Pervus Ellison at best.   but Bynum will be a factor as he matures,  maybe not Shaq good but somewhat comparable
