If you are an elite player, a club will find you, promote you, and allow you to reach your potential. The problem lies when sorting the next tier of players. That is where connections and networks overwhelm any meritocracy. High school and college coaches don't care who the bottom 10 -15 kids (of 45-50) are because they don't impact their W/L record. They can use those spots as favors for whatever reason they choose.
