I would respect him if he played the second round too. This is a 72 hole competition, not a golf outing with your buddies. He should have played today, and missed the cut, like the others who are playing poorly.

It sets a poor example for the many kids that follow golf... and there are quite a few kids that post on this site that play competitive golf. It sends the wrong message, that you can just walk away with your scorecard in your pocket. If you tee it up, stand by your score. I see too many players in tournament golf who "no card" when they play poorly, and only turn it in when they play well. To me that is poor etiquette, and makes a mockery of the game.
