Everybody makes plays, as the game consists of them. A "playmaker" is someone who can do so on a near-whim, through a mix of sheer physical force and vision. When we discuss playmakers, we're talking about perimeter operators, guys who don't depend on teammates for the rock.
In discussing "dynamic playmakers," statistical efficiency need not apply. Dwyane Wade makes many mistakes, but he will be somewhere on this list. Rajon Rondo would appear to take regular-season games off, and he will certainly be on this list. A dynamic playmaker is not necessarily a consistent playmaker.
