GS Indicates a Grand Slam winner
* Indicates a current or former #1 player
Patterns (according to Bud):
► Murray should have definitely won a GS title already with his record. Big choker and/or underachiever in the important tournaments??
► Check out Borg's career record... mighty impressive when looking at Federer/Nadal!
► Nadal's percentage is higher than Sampras
► Roddick is a major overachiever who definitely maximized his talent!
► Chang was an even larger overachiever than Roddick. Fairly low success over top 10 and never reached #1... but won a GS title
► Kriek deserves the over-overachiever award. He possesses an anemic 23% win percentage over top 10 opponents while also winning 2 GS titles!
