Surf has an open door policy when it comes to girls leaving. We have had a couple of girls leave mid season to join other ECNL teams with no repercussions. It just needs to be approved by both DOCs and the league. So, the idea that these girls were put on the ECNL team just to lock them up, makes no sense.

Most likely 1 '04 "stud" was given offer/card to occasionally play with "03"s and then a couple of parents butts/egos were hurt leading to issuance of a few other cards and phantom rostering to placate said bruised egos. Probably had nothing to do with "locking" '04 players into a club. Surf philosophy similar to Doritos advertising; "go where you want...we'll find more"
