Chronological vs Physiological Age
Our current hodgepodge system of sport in the US tends to reward early physical maturation and forget about those that reach their physiological prime a bit later in life. All young athletes deserve and need fundamental movement skills and physical competencies. All deserve to learn the fundamental skills of a sport, rather than be pigeon-holed into one position at age 13 because we have no idea where they might fit into the puzzle at at 18 and especially age 24. And what about intangibles like leadership, tenacity, drive, the ability to thrive under pressure? Size matters, but it isn't always the best predictor of athletic success or even best sport choice later in life.
