re: True NBA center piece players...

There aren't many.

Obviously Lebron and Durant. I love Paul, George, and Love but you can pick at all of them (maybe not Paul if we're past the point where angry hornets fans are saying Paul's knees are done?). In spite of his rep for being soft I think you have to wonder if BG might be emerging as a potential franchise player. Rose and (to a lesser extent) Westbrook have current injuries hanging over their heads if you want to downgrade either.
