While the test may give some indicators, I think this practice of trying to specialize kids for certain sports is just baloney. There are so many examples of athletes who are / were the best in their arena that certainly were not the ideal "type" for their sport. Just look at Wayne Gretzky - 6'/180lb. Barry Sanders - 5'8... For athletes like a football quarterback, it's not even about being good at a single thing (fast-twitch sprinting). It's such a multi-dimensional position that just having fast-twitch speed is not going to guarantee you're the next Joe Montana or Tom Brady. And finally, so many people have the talent but don't have the work ethic and drive to make the most of it. The people who are out there every single day for hours - throwing, kicking, sprinting, etc. That first 10% might be genetics, but the rest of it is blood, sweat, and working so hard some days you come home and puke.
