At what age do you think your kid started to really understand the game and tactics and displayed that intelligence on the field? Curious to see if there is trend. For my oldest kid, I'd say around the end of U13 after a full season playing 11 aside. In her U14 season, you could just see the confidence, poise and continuing growth in decision making. Ability to play multiple positions and not miss a beat. Just a pleasure to watch as a player now at U15.
