TSO: A big part of the "problem" is our haste to identify/anoint "prospects" at ridiculously early ages, often to the exclusion of kids who are BETTER later. Then, as if to justify the early selections, we continue to select and promote those same kids, year after year after year, even when they don't age/grow/mature into high-level athletes.

This is NOT a knock on any of these you've named. They're NOT the problem. The problem is a system that effectively discourages and excludes thousands of kids by ages 10-12.
