That it’s difficult is obvious, but part of what makes it difficult is impossible to see. The mental game. Some players thrive under pressure, while others crumble completely. Having the mentality to win major events is no good if you don’t have the game for it and having the game may not be enough if the nerves and stress cause too much trouble when the heat is on.
Rory put a lot of pressure and expectations on himself, but it surely doesn’t help with all the media attention around his lack of major wins the last decade. He said in the interview that having all those legends of the game (Tiger, Jack etc.) saying he will win it one day just added to the pressure. They probably meant for those to be words of encouragement, while they had a negative effect on Rory.
Ever since Tiger dominated, new promising players were “the next Tiger”. Rory has as good a game when he’s on, but Tiger was at a different level, over a long period of time.
Anyone would be nervous in Rory’s shoes last week. How it would affect their game is very individual.
