First off, as has been indicated, this is just a marketing ploy to hype the last few events of the season. Secondly, it can hardly be a playoff in the way they work in other sports because there are MANY individuals all playing in the same game each time. In tennis it is one player against another and a loser goes home ( or in doubles, one team). In football it is one team against another and the loser goes home. But golf isn;t played like that.
I'm sure the reason they don't do it as a series of heads up match play events is that few people would watch it if Tiger and most of the top players were knocked out early. Also, match play events can be over after ten holes. So it comes back to the revenue stream.
They change the rules each year trying to make sense of it so I'm not sure what is different this year, but last year Vijay was able to win it by finishing dead last in the final event. At a glance it looks like a string of second place finishes could win it given poor perfornace by the right players in the last event. If they have jiggered it so everyone get "restet" for the tour championship then how could only the top 5 have a chance to win it? And if they did that, does htat mean one could now win the first three and lose on the Tour Championship and lose the cup?
It's just about making money for FedEx, the tour and the networks which carry the coverage. I don't think the players care all that much about it, frankly.
