Why can't players that "guest" play be out to do it for the experience??? There are so many positive experiences that come out of guesting for 10/11 year olds!!! Maybe it isn't about "greener pastures" for some. It gives them the opportunity to develop and become a well rounded player. They may be put in a different position then they normally play on their club. They get to meet different girls and coaches and adjust their style of play to different players and coaching styles. Not all parents are blinded by the glitter of a "big" club. Some are, but most know it's a business. In my opinion just because you guest play doesn't always mean their looking for "bigger and better". I am sure these big clubs want the best of the best players to guest, just like one person said, you need someone that will add to the team and make a difference and help them win. Winning attracts players to their teams for the future. It really is a smart business move.
Now I ask the question, about your comment about taking time away from the "paying customers". May I ask if this was a scrimmage your speaking of or a tournament. From what I have seen, typically a team will bring players to tournaments, due to numbers issues, and with a potential of having four, five or even six games, fresh feet are better than tired feet.
Just my opinion on guest playing, not saying its right or wrong, but just what I think its all about
