Well this came out today to TM's with the 2017 rules (the one on the website is last year's I believe)
See the portion I copied and pasted below...
Less than pleased....not what we expected.
CLUB PASS RULE:
If you have a player(s) from your club that is (are) playing on your team (and are age appropriate), write the player name and player id# on all 3 copies of the game report. Players MUST HAVE THEIR PLAYER ID CARD (US CLUB) in order to be eligible to play in the game. Players CAN ONLY PLAY IN ONE EGSL GAME PER DAY. There is no special card for the club pass, the player just needs their player ID cards and medical release form. ONLY US CLUB CARDS ARE ACCEPTED IN THE EGSL. ECNL cards are also accepted in the EGSL. No other type of player card is acceptable.
No player card. No game. For teams playing 7 v 7 (2007, 2008) and playing 9 v 9 (2006), your teams you are allowed to CLUB PASS no more than 4 players to your team. For all teams playing 11 v 11 (this includes ECNL players), you can club pass no more than 8 players to your team. All players must appear on your EGSL roster.
