You can only have 25 players on your NHL Roster.  There are still teams with more.  If I don't receive an e-mail with your new rosters by December 17 you will be released for a new general manager.

Flyers 26 players
Islanders 26 players
Leafs 26 players
Hurricanes 26 players
Predators 26 players (only 2 centers)
Bluejackets 30 players
Wild 27 players

You can only have 25 players on your NHL roster, and only 20 playing with 5 scratched.  The rest must be on the farm system.
