I believe the message is he believes American kids need to learn to be more instinctive. In football plays come in from the sidelines. In basketball there are plenty of timeouts for crunch time. In baseball pitches are called. Coaches position fielders. Sports like hockey and soccer rely on the players knowing what to do. Especially in soccer where the players aren't on shifts like hockey. There's little opportunity in soccer to have a coach think for the player.
