I think this would be a great idea. I, for one, would be Deputy Commish for a league (or 2-3)...for free.
I think the main duty would be to keep unmanaged team rosters up to date, rotate players to keep player utilization appropriate, keep default lineups accurate, and perhaps play the games for the unmanaged teams (or at least initiate the robot to play the games as soon as the games are activated each week).
The Deputy Commish could field trade offers, screen them, then email MBravard for the official approval of trades. This would allow the offers to unmanaged teams to be screened for Mike, with bad trade offers rejected quickly.
I don't think I would want the Deputy Commish to initiate trade offers however.
I think a Deputy Commish could help Mike keep the unmanaged team problems to a minimum.
