Way too much being made of Tiger's "antics" here.
Case in point: We wouldn't be thinking that about the great Jack Nicklaus, would we?
Think again. Battle at Turnberry, 1977. Jack was a lot older then than Tiger is now. Have a look at what happens after Jack's tee shot.
*gasp* Did he slam his club? What a baby!
So, are we going to say that Jack needed to 'grow up'? Of course not. It was the great irony of Rick Reilly's piece referred to above during the British Open at Turnberry this year. Clearly, Mr. Reilly, amongst others, have clearly forgotten that the previous 'great one' was always cursing and slamming his clubs. No one even questioned Nicklaus' etiquette. It just comes with the territory of the game of golf, especially among those who hold themselves up to a certain standard of excellence.
We also need to keep some perspective here on Tiger's *antics*. Have a look at any other major professional sport, and you'll find players with names you've never heard of making incredibly routine plays and showboating like they just won the Grand Poohbah Championship of the Universe. By comparison, anything Tiger displays out of anger or joy is tame.
*edit* We've already been down the Y.E.Yang road earlier in the thread. Yang made a no-no of his own in not letting Tiger finish out before wining the tournament. So, if Tiger moved, so be it. tit-for-tat.
