There are two kinds of point guards in the NBA, natural ones and ones that had to be taught how to play the position. Despite what you might think, neither has an advantage over the other. Knight is not a natural point guard. He sees the bucket and scoring chances for himself more than anything else, which is only a bad thing if he never learns how to play as a true point guard. Williams, on the other hand, can control the action while sprinkling in his scoring when necessary. And when he needs to be a bucket getter, it's also a very natural thing for him.
