Jim,
You're being kind of obtuse. I'm a 12 handicapper and I'm very disappointed if, on average, I'm not closer to the hole with a 9 iron than with a 3 wood. Now if I was a really good player, I'd be even more upset if that wasn't the case. Of course for players who hit the ball as well as each other, the longer hitter will be the better player, if their short game is the same. To argue that long hitting isn't an advantage is perverse. There's nothing wrong with that, by the way. There's no reason at all that power should not be an advantage in golf, just as it is in most (all?) sports. And of course, sometimes a freakishly good short game can more than compensate for length (but please don't pretend Jordan Spieth is a short hitter, he isn't). On average, however, the longer hitter is the lower handicap and for good reason.
