Man, how far do you think Nicklaus would have been hitting it with this swing (circa 1963) and today’s technology? I’m guessing he would be Bubba Watson long, but infinitely more controlled. The most interesting thing here is Nicklaus’s backswing. Definitely not what is taught to young prodigies today: too much leg and hip movement (how about that left heel lift?), shaft inside, club across the line at the top. But what the hell, it worked better than anything anyone else was doing, and became the model for a generation of wannabe players. I still can’t get over the size of those thighs.
