Whereas Rondo is doesn't shoot enough (or even provide a threat), Westbrook can definitely shoot too much.
Westbrook shoots alot because he's a scorer. Are you saying it's a flaw for Rose, Kobe, Durant, Wade that they shoot alot? How do you score points without shooting?
Rondo will never be elite if his main skill is being a pass first point guard. That basically means you have to rely on having good teammates. What happens when KG, Ray, Pierce are gone, who are you going to pass to? Elite players can do it themselves if need be.
