You dont think Bryson or Bubba or JT are trying to kill it? JT has been quoted (in the Altus Performance podcast, "Earn Your Edge") as saying that sometimes when he is feeling confident with his swing, he stands on the tee and his only thought is to hit the ball as hard as physically possible.
The goal is to shoot the lowest score, regardless of how much effort it looks like you are putting into your swing.
So the highest lofted club in your bag is a 9 iron?
How do you play greenside bunker shots?
What about a 30-40 yard pitch shot from the rough to an elevated green short sided with no way to run the ball up low?
