You are right. Tiger has not beaten Jack’s record. Yet. Barring some reason for Tiger to give up golf, it’s pretty clear he will.
I am LOL at your requirement that in order for Tiger to be REALLY good, he must first live through a horrible car accident (the current one does not count) and then have a remarkable career.
What year are you suggesting that Ben won the grand slam, as the info I have found shows that he grand slammed for his career (which Tiger has done twice already), but not in any one year?
Tiger the serial adulterer was pawned at Shanghai, the Masters and U.S. Open by Phil and by a 16 year old Italian amateur at the British Open where Tiger failed to make the cut.
