Today, Janelle and I watched Connor play slightly more organized versions of those summer games. There was not an official score, the clock ran down no matter what, and the five teams rotated around so that each one had a chance to play against the others. It looked like the players were having fun.
At present, Connor towers over most of the other players. He's about at the age where my height plateaued, but he still seems to be growing. While he has the build for it, he has not cultivated the skill yet. However, I saw improvement in his play just through the today, so perhaps he will be able to play the game at a higher level than just pick-up games on outdoor courts.
I just hope that he has fun with it while learning teamwork and sportsmanship.
