It isn't often a sport gets a complete makeover. Singular moments are rare, but over time the impact of certain individuals and how they play create indelible memories.
In college basketball, this was best exemplified by the Larry Bird/Magic Johnson NCAA Final in 1979. The NBA had Bill Russell and the Celtics in the 50's and 60's. When a reboot began with Bird and Johnson, Michael Jordan joined them and created an era of his own. Football experienced a similar revitalization with the arrival of the West Coast Offense and Joe Montana. Baseball has gone through multiple reboots recently, though few have had a positive spin. Steroids and strikes have had bigger impacts on the face of baseball than the arrival of a dominant player or a new method of playing the game. Sabermetrics have been a net positive, and even my interest in the sport has grown over the last 15 years because of the new math which opens a window onto what real productivity is in the sport.
I haven't watched much of the Olympics, but I've been fascinated with Ted Ligety for some time. In a sport which is usually decided by hundredths of a second, Ligety crashes down slalom courses with seeming abandon and winning by what can only be called massive margins. His dominance is of the type rarely seen in any sport, let alone skiing.
Ligety is one of those people who has reinvented his sport. I did a limited amount of downhill racing in my youth, and I remember the coach telling us the point was to find the fall line and make the course as short and fast as possible. For years, that was the formula for reaching a victorious finish, often by slim margins of a second. Giant Slalom, in particular, was usually a visual of tight turns around the gates and keeping as close to a straight downhill line as you could accomplish.
Ligety, on the other hand, takes wider turns and gets as parallel to the ground as he can. This approach has turned the US team into a powerhouse. Ligety creates power on short portions of the course where others coast briefly, and as a result he is able to smash the competition by moving rapidly, and effectively, from turn to turn. Long ago, someone told me Beckham was a geometry genius because he could figure out how to get a ball from Point A into a goal around the wall. I doubt he understood much about geometry at all, but he certainly understood how to make a ball do what he wanted it to do. Ligety, by the same measure, is a physics genius. He's determined how to turn portions of his run from potential to kinetic energy and power himself faster than others are able.
Most of the Olympics has been a bore, outside of hockey and Ligety.
