- Kenny Perry could have won the Masters had he not bogeyed the final two holes in regulation.
- Phil Mickelson could have won the Masters and could have had one of the most famous final rounds in history after shooting 30 on the front nine. His double bogey on 12 cost him that shot.
- Mickelson could have won the U.S. Open in heroic style with his wife going through cancer.
- David Duval could have comeback from nowhere to win the U.S. Open. An unfortunate plugged lie that led to a triple bogey early in his final round really hurt his chances.
- Tom Watson, 59 years old, could have been the oldest player ever to win the British Open before a heartbreaking bogey on the final hole sent him to a playoff against Stewart Cink.
- Tiger Woods was in contention at both the Masters and U.S. Open. Poor ball striking at the Masters and terrible putting at the U.S. Open killed his chances.
- Tiger Woods could have won the PGA Championship for the 5th time before being stunned by Y.E. Yang. This was the first time Tiger ever lost a major with the lead going into the final round.
