People tend to get overwhelmed by talent, and it makes them forget that talent is only useful when it's used right.
That's what the Rose/Rondo debate boils down to--Rose is the more talented of the two, but Rondo is BY FAR the more intelligent and resourceful one, meaning that he gets much more out of his talent than Rose ever can. It's great to be talented, but it's far more important to have the ability to use that talent tastefully.
Going forward, Rondo's always going to have the edge mentally, and assuming they remain relatively equal as athletes that means Rondo's always going to have the edge on the court for as long as they both play.
