Yes that would be interesting. I did a little investigating and could not find anything like that. But good players are playing legion at some point, whether junior or senior legion. I agree that legion has lost some momentum, but I just don't think it's as dead as this thread is making it out to be.
Also, assuming the American Legion stats are correct, the highest ratio of travel/club players to Legion players in the MLB is 2:1. You can check my math on that.
