I understand that Woods and Mickelson don't see eye to eye, just as Darrend Clarke and Lee Westwood are known to be best friends. Does anyone know why that is, or whether there was anything specific that caused it? Are there other pairings that cause friction on tour? I'm always fascinated to see how the pros behave when together - either on or off the course - because of the insight into their lives. Maybe I'm a wannabe - can't deny that.
