You're betting that Dustin Johnson (5th ranked player in the World) can't get 4 wins in the next 12 years?
He has won pretty much every year, including this one. Do you have some insider medical knowledge on him?
Yet still PF, if DJ were to be that player in say, 4 years time... and IF "loses" his bet... the point is still made: Such is the nature of today's elite competition that the worlds best players can't/don't accrue what the world's best did in the eras previous. One can say that the mettle of the last years' World Top 10 is not up to it or that the total competition is better and more diverse or that huge purses and revenue streams allow just a few victories to earn equal rewards with that only multiple winners could achieve of eras past.
And even if two or three more do as DJ may, gone it seems are the days when today's leaders win as much as Mickelson, Watson, Singh, Trevino, Miller and earlier still, Middlecoff, Casper, Demaret did when they were the World's best....not to mention the toffs of Woods, Snead, Nicklaus, Hogan, Nelson, Palmer...nearly gone are the days when a great player wins 3 or 4 times in a season.
