Golf is a very technical sport and the casual fans eyes often glaze over when pundits get into the intricacies of "golf swing mechanics". But this gif does a good job of showing the evolution of Tiger Woods' swing, from his casual drive as a three year old to his rigid posture today.
Now, I may never have held a golf club before, but his swing was definitely less rigid ten years ago than it is today. Now all we need is a similar breakdown of Padraig Harrington's swing to see why he stopped winning majors.
