Just like last year, here are a few of the common questions that spring up every season.  If you could enforce as per below, then we'll maintain some level of consistency with regards to the following points:
 

• # of substitutions per game - we have always played with unlimited substitutions in our league.  Substitution is on possession.
• # of substitute players during a substitution event - some teams have a ton of players showing up to a game and so subbing only 3 players at a time may not be the most logical otherwise they'll be subbing all the time and slowing the game down.  I think it is best left up to your discretion; if you have a preference for only 3 at a time or no more than 5 or 6 at a time, that is fine, I would just ask that you speak to the teams before the game so they know this is your expectation.
• Subs at center line - I think most teams send their subs from their bench to the half-line, but if they do not and this is something you would like, please feel free to also request this of the teams.
• Game length is two 45-minute halves.
• Game start time for entire season is 7:15pm
