You guys are nuts. He didn't admit to breaking a rule. He admitted to moving the ball back 2 yards like it was no big deal. If he intentionally broke a rule to gain an advantage, do you really think he would talk about it so nonchalantly? Absolutely not. He was obviously playing under 26-1, keeping the line from the hole to the water...he obviously confused the rule. He didn't lie and say he was trying to play the ball as close as possible to the original spot. He signed the correct card according to the rules officials...it wasn't until after the round was over and he had his interview that they "changed their minds" and got the call right. At the time of card signing he signed the correct card....there is no way he should be DQ'ed with the new rule and no way should he DQ himself.
Scenario: It's the NCAA championship basketball game. A player is fouled during a shot attempt with 1 second left and his team is down by one. NO call is made, game over......should they review it after the game is over and call a foul.......then have him come back on the court, make both free throws and change the winner?
He made a mistake....it wasn't done maliciously and he has been punished greatly for it....More than I feel, personally, given how it all played out.
Please get off your high horses and stop asking for him to "DQ" himself.
And I think a lot of the commentators like Nick Faldo are showing very low class when asking for Tiger's head over this.
