There are very few reasons to reschedule a game.  Please review

East Central Rules and Regulations

Page 7:  Game rescheduling and postponing procedures are for all East Central Leagues

Canceling or rescheduling a game will need to be done two weeks prior to the scheduled game date so the times can be adjusted for the clustered games. 

The schedule manager for each club should be the only person submitting reschedules and they should determine if the request to reschedule the game is a valid one.
