An old friend of mine who was a high school and college basketball coach
Can't really add to the stuff you said on Guardiola as it's pretty reasonable and I agree with it. Just wanted to say I'm a big fan of US high school and college coaching - at least what I get from it one the web. As a U17 Volleyball coach I can't find a lot on coaching from Germany, because the sport isn't that big and my states youth coach education seems fishy at least, so I have to take a lot of ideas and basic techniques from football and handball and then kind of translate them. But as Volley is bigger in the US, I get a lot of material from American sources, especially on technical and tactical stuff and it's miles ahead of the Volleyball youth coaching over here.
