strange that you needed to check Diablo!
re Donald & Westwood, it seems like such a media circus with them now it's getting totally out of hand. it's getting the same for andy murray in tennis (although rather different circumstances).
Westwood - amazing ball striker so he'll normally feature among the top 10 on difficult courses, which is where Majors tend to be played. however, given that 3 are in the US normally on very fast hard greens, you need to putt exceptionally to win one. Westwood will either need to putt out his boots one week or just play such good golf that he wins anyway (less likely but McIlroy has the potential to win in this fashion).
Donald - bit shorter off the tee and slightly more erratic, but basically pretty steady, plus an incredible short game. he's also about 5 years younger the Westwood, and this year has won at least tournaments. so i slightly favour Donalds chances.
the overall standard is so high that many players can have a good week and win. more than anything, the guy who wins needs a bit of luck. sure keegan Bradley played well, but first, Dufner finished with 4 bogeys in reg play to the 18th and second, Bradley got a bit lucky on 17 & 18 in the play off (just carrying the water, esp on 18) but fair play to him he won it. darren clarke played awesome at the Open but anyone could see he massively had the weather in his favour - look at the conditions rickie fowler had for almost all 4 rounds being in the opp half of the draw.
why should westwood and donald win or have more chance or winning than players like hunter mahan, nick watney, adam scott etc etc there are just so many good players out there. maybe they won't win a major. they both seem like great guys who have had outstanding careers and conduct themselves well and are trying there hardest. if they don't win a major, then to a degree, so what?!
