R u kidding me...have you looked at the leader board...who do you see in the top 10 under 30...only 2 out of 10 (louis and hunter both at 29) I might believe you if..... lets say Gary Woodland (who had to withdraw from a wrist injury) or rory mc +1.....was up at the leaderboard....
your theory just doesn't hold water atleast not in golf...but maybe in basketball, baseball, and football but not golf... did you see norman and watson almost win a major
