I don't view the weekly play on the Tour as "entertainment" but as a series of athletic competitions that, cumulatively, help us to identify who are the best players in the game. In the 1970s, when most Tour golfers used balata balls and most recreational players used rock-hard, long-flying Top-Flites or something like them, there were (effectively) two different games. In terms of competition, and shot-making, I believe the game played by Trevino, Watson, Nicklaus and Co. was superior to today's smash-and-gauge game, but that is of course a subject on which reasonable people will differ. Age is a factor, too.
For millions of us, the most interesting events of the golf year are the four major professional championships. (The Ryder Cup is a separate category.) What makes these weeks so special is what playing in them, let alone contending or winning, means to the players, and the demanding, interesting and often time-honored courses on which they are played.
Pebble Beach and Cypress Point make you want to play. Spyglass Hill - that's different; that makes you want to go fishing. JACK NICKLAUS
