I did not watch Tiger's apology. I do not care. I enjoy watching Tiger play golf, that's it. I don't think he owes the public an apology. The only people he has to apologize to is his family. Of course then he issues an apology (as the public unfailrly demands) and people claim its not sincere. Like msot apologies that are forced, it probably wasn't all sincere. I'm guessing he's truly sorry in regards to his wife, but then again, its none of my business.
Tiger did not cheat the sport of golf. He did nothing illegal. He certainly has lots of issues in his personal life, but that's what it is...personal.
Tiger owes us nothing.
