He's 6'3" 200 pounds and a big, strong athletic guy. Most golfers are going to hit it REALLY short trying to emulate his swing. It works for him and the reason he hits it so straight is he essentially holds that clubface down the line cutting a little across it for as long as possible. He will never miss left and in fact has to really contort his body to hit draws but that's a good thing. As a right handed golfer you want to completely take the left side out of play. It's what Hogan wrote his entire book about.

Club face open ? WTH does that mean?

His swing is hideous
