I think LI teams are tired of playing each other at these showcases. I understand that a lot of great kids come from Long Island but to play each other does not make sense. Maybe if you meet in a playoff or final that would work but I think these kids want to face kotjer kids from different states even if it means winning or losing some. just my opinion but I think most people feel the same way, even teams from other states.
It's all about getting looked at by coaches. If that's where the coaches are going, that's where you should be whether you're playing teams from LI or Mars.
