Tour Winner
Because he is a professional athlete who has dedicated his life to improving his strength and technique as opposed to club golfers who only play once a week. Everyone can hit the odd good one (I've hit 300 yard 2 irons on links courses) but for people to claim their average is 270 or 280 is pretty unlikely.
For sure I have the physical ability to hit the ball as far as a tour pro does. But I have the technique of a mountain goat. Thats what I believe makes the difference between a hacker like me and a tour golfer.
