I think as a coach I'd get the other coaches that aren't him involved. Ask them if they feel as you do, and if so go to the commish or board as a group, probably after the season is best.
As commish, if you came to me as a group I'd use it as an excuse to shake up the league (or get out of being commish if the board was being ridiculous).
