Adidas....they were afraid that the kids would get to "close" to a coach if they coached them for a few years. It would then be easy for the coach to go to The Bridge and take the whole team with them. Also if coaches didn't coach the way the DOC wanted them to, they were gone. You had coaches who never questioned the DOC on training, tournaments or anything.
Having coaches coach 2-3 teams was all about the money and ability to control the coaches.
