Spin Move are traveling violations

I actually called a travel on a spin move in a HS boys reserve game this year, and the coach started jawing it was a good move. I told coach to watch that spin move next time, and tell me how it's NOT a travel. Coach just couldn't see it. My partner noticed the next one, and he called it. I think in that game alone we called it about 10 times and both coaches just couldn't get it. The AD was complimenting us after, saying the first one caught him by surprise, but the rest, he started to see the trend, and was just dumbfounded neither coach could figure it out!
