Okay, I'll try not to be silly or make no sense this time. And thanks for those insightful observations, btw. First of all, golf is and always was a game of individual tournaments. It's futile to try to construct a playoff scenario to determine a "tour champion," a fact that the numerous adjustments to the current system will attest to.
And yes, the Tour Championship has been around for years. But before the Fedex era, it was simply another tournament that happened to be named that way. There was no effort to frame the winner as some kind of actual tour champion the way the playoff system does today. It was just a cool sounding (albeit a bit pretentious) name like The Player's or the Master's that held no actual significance beyond the single tournament. The difference now is that, yielding to the demands of a mega-money sponsor and preying upon the unwashed masses insatiable need to identify "the best," this current ridiculous system was put in place.
Of course, all of this is just my opinion, however silly it may be. Naturally, we all have the right to see the "playoffs" in whatever light we may choose, whether we view them as a trumped-up sham or a legitimate method of identifying a true Tour Champion like Bill Haas, Brandt Snedeker or Billy Horschel.
