I think there may also be a correlation between people having the same coaches year to year and people staying at home with their local clubs--which, in turn, affects the local clubs' win/loss record. People form relationships with other people, not with organizations...when players don't know from year to year who they're going to be working with and playing for, they don't have much to lose by looking elsewhere. When they find a team and a coach (or coaches) they enjoy working with and there's a consistency from year to year, I think most players are less likely to jump from club to club. A solid player/team/coach relationship has staying power, whereas a more clinical rotation of players and coaches doesn't do much to inspire loyalty.
