There was a follow up article in golf.com today on this. Seems a reporter asked Tiger about this yesterday, and he said that Sean is his friend, so why not help him? Go to golf.com to see the full interview and story.
I think this is another of those differentiators that sets golf above other sports. Golfers truly try to help others, from the communities that tournaments are played in to their fellow competitors. The thinking is that the betterment of society, and improvement of those I compete with, ultimately makes me better is so true.
I have to tip my hat to Tiger...
