I would like to suggest that youth coaches start to talk about and encourage their players to watch and support the US National Teams. I often have my players watch our national teams play and then we discuss the game at the next practice. I think this is a win-win situation. The youth players learn from watching the top players in the country and hopefully these youth players end up being life long supporters of our national teams. God knows we need more support in the stands!
I do. In fact, on our team calendar online, I include televised national team matches (and big MLS and Champions League ones too).
