I guess that my definition of sangbagging is not the same as others. In this case it appears that a player advanced through the ranks all the way to Legend in a short period of time. That means he has to play against all the best players in the site, he more than likely is restricted at this time in club selection.....so what is the deal. If he was a true sandbagger he would have stopped his tier advancement at the master or even pro level and have been thrashing everyone from the short tees.
In this case he advanced to the top tier in a short period of time. True he might have won a few times as he moved through, but if he played with good players, maybe even used their accounts while he learned, he still did it the right way.
He didn't set up a new account, gift himself all good equipment and take advantage of the pro level to win, he moved forward and became a Legend so he plays against the best, what Russell said above is right now, we should congratulate this young player in doing it the right way instead of trashing him for not being a sandbagger.
