I always liked the Par 3 contest as an added fun touch to The Masters. But, given the fact that no one who has won the par 3 contest has won the green jacket makes me wonder how hard the players try to win the "fun contest"?
I know that most of the pros look at this as a family/fun event. You may notice that some pros even let their kids putt during the contest. So, in that respect there are no competitive juices flowing.
