Who benefits the most
Much more to life than running folks and HS kids.
Don't get me wrong, running, racing, training, traveling to races and meeting people into athletics is all good - great in fact. That time, at a high level, doesn't last very long though. What does is your time working, amassing wealth, living in our system that looks highly upon those that have a good or excellent education, can make good decisions, problem solve, interact/motivate/relate with people. If you are a good student and athlete it's an easy decision and so too is it for the HS quote phenomenal/next great etc. GET an education and let your athletic talents get you that education.
Some of these HS stars that have opted to go pro probably have regrets on missing out on the experiences that being part of a team that University offers, and so much more. Track and field doesn't pay well. An education does. We will see if the recent few that went pro very early actually do get an education that translates into employment of significance down the road.
I wish them well and best of luck.
