A lot of the swing changes were due to his injuries though - his last major win prior to this he won an 18 hole play-off on one leg as his knee was fucked. Major rebuild on the knee then the swing changes started.
Tiger is the GOAT for me...... when did Jack ever win a major by 15 shots like Tiger did? Jack was great, but Tiger at his best was on a different planet entirely - screw what the stats/records say.
