What an odd sentence. Sounds like Tiger was desperately trying to say something positive about Bubba but couldn't think of anything specific.
I was thinking along the same lines, except maybe Tiger chose his words quite carefully and was perfectly accurate.
He did not say that BJ knew world politics.
He said that the things he knew to describe world politics were brilliant.
What he said, quite literally and unhesitantly, is that the Toon is good at story telling when it comes to geopolitical topics.
Nothing more, nothing less....unless you consider the fact that he had just protrayed his disbarred golf partner as a cheat, and trusted him only so long as he could see what he was writing on the card...well, I guess these could count as qualifiers.
I think Tiger said exactly what he meant to say, it was a top shelf slam....and brilliantly executed :)
