The reason why the Knicks even have a dilemma, at the small forward position, is because Walsh drafted another small forward. This is how I think the minutes should be distributed:
Bench: PG Robinson, SG Richardson, SF Gallinari, PF/C David Lee(Lee played center in college, he can do it in the NBA).
Forget Curry, he sucks. Stephon Marbury & Nate Robinson >>> Chris Duhon
The minute that Quentin Richardson gets one of his usual injuries, put Roberson as a backup shooting guard.
I know I left out Balkman, but it's impossible to fit 5 small forwards into an 8-10 man rotation, unless you want people to play out of position.
