J.J. improved his overall game dramatically while at Duke.
Boozer didn't drop to the second round because of a perception that he hadn't developed at Duke but because he was thought to be too short to effectively play the 4 at the NBA level.
This whole "benching" a three-year-starter thing is a bit over the top, IMO. Instead of playing 28 mpg as a starter, Paulus is going to play 25 mpg as a sixth man.
