Graeme McDowell essentially came out of nowhere last year, Lucas Glover won in '09, Angel snuck up and won it in '07, Does Michael Campbell even still play (for those that don't know, he won it all in '05)?
Todd Hamilton, Ben Curtis and I still can't spell the guys name from last year that won the British. Your statement sounds pretty golfballs03, but winners prove that the favorites and top dogs don't even win the US and British half the time. I'd have to agree with BMFPV that it's largely based on setups from the USGA and the R&A.
