how will derrick rose help the chicago bulls in the 09 season?

Great leadership. He has Jason Kidd's personality and can make everyone around him better.

he won't

Depent on what are they going to get by trade Hinrich~
I wish they can trade Hinrich, Larry, and Tyron for Beasley~

make the playoffs 48-34 15+ better than last year

Not much, the teams record will be ALOT better than last year, giving they got a new coach, and greatly underachieved last year (Considering some picked them to win the East last year)......but Im sure Derrick Rose will get alot of undeserved credit for the Bulls turnaround...
