Question: Given the choice of one or the other, do we want good NBA players or players who fit well into CBS's system?
(Obviously, in a perfect world, we want both).
Good players, no question.
This whole thing about "players who fit the system" is a bit silly, to me. I agree that you want players that fit with each other, like you want some drivers, some shooters, some defenders, some rebounders, some passers, and hopefully some guys who can do more than one of those things well.
You get good talent, and a good balance of players who complement each other's games, they'll fit the "system" of any good coach.
