Simple Waivers Proposal...

1) After trade deadline (and before September), any player can be placed on waivers.  This would be done public, either in a master thread, or a separate thread for each player.
2) Other teams have 72 hours to make a claim on such player. 
3) If a player isn't claimed by any team in either league, he can be traded until the end of the month to anyone.
 If a player is claimed, but only by one team, the player can be traded only to the team that claims him.  If a player is claimed by more than one team, the club with the worst record in that player's league gets priority (player's league has priority over other league) -- and the player can be traded only to that team.
4) A decision on the player must be made within 72 hours of the claim.  If, within such a time frame, an agreement wasn't posted by both parties NOR was the waive canceled by the waiving team, then the player is considered to moved to the claiming team in exchange for nothing.*
5) If the player on waivers goes unclaimed within 72 hours waiver then waiving club must have the player released outright or traded to any team within the next 72 hours.
6) Players may not be put on waivers after August 31st but all other waiver transactions will finish their time frames until completion (rescind waiver, trade, release, transfer).
7) A waiver may be canceled only if the player was claimed.  Cancellation of the waiver by the waiving team within the 72 hour negotiation period means that the player can no longer be on waivers that August and stays with their team.
