There's lots of issues with negating a contract grinko. You are brand new so I don't throw the blame at you, rather those that suggested you send in a ticket, and the commish if he sent in a ticket without consulting the world.
1. Like was said in your world chat--others were bidding on him during free agency and lost out. Then, you would have him in alesser deal than others were offering.
2. The deal wasnt that bad. There are worse deals in probably every HBD world that owners have to deal with. To turn over this deal could cause all hell to break loose.
Its my opinion that the only time WIS should step in is when an owner intentionally trashes the team--releases all their players, signs garbage players to huge contracts--and otherwise goes about trying to purposefully trash the league. This is the kind of deal nearly everyone had to work around in this game. Its part of the game.
