Only the admin can add teams (I created a test account to confirm this). sully, are you up for us just sending you the teams via PM and having you enter them?
I also noticed there's no way to set it up to track wins for a team, so it looks like it'll be the 14 skaters plus the goalie. Could the goalie then be set to get one point per win and an extra point for a shutout? That seems pretty similar, I doubt many would have picked a goalie not from the team they were going to select.
