More than likely a player + a first round draft pick.
The player will likely be one of Suban, Michie, Crozier, Mellington.
Are you talking about Jack Riewoldt?
If so one of those players isn't going to cut it. It would be a player like Fyfe, Hill, Morabito, Mundy. You don't trade dual coleman medallists for pick 17 and spuds like Suban you fool.
