G.O.A.T.
OK, the grade school vs grad school analogy can only be applied to a certain extent, much like the Circle becoming obsolete, inappicable at certain level. Let's not get carry away with it I imagine at ATP level, the Directionals become a little crude themselves. It seems like to me that the winners at ATP are those who break the rules, take risks the most and somehow still manage to get another shot in. They're the successul models.
