banditodad,
In VA and NC, AAU is more popular. I know most teams had already made housing arrangements back in Feb for AAU Nationals (we did). I would assume that is the case with them.
How does your team work the 'A' team and 'B' team? It seems like there would be a LOT of problems with this concept, especially if the 'A' team can call up 'B' team players.
