Do you mean other than Judd, Dangerfield, Ward, Thompson, Dal Santo, Ball, Prestia, Kennedy, Burgoyne, Ebert, Vince, Tyson, Polec, Beams, Griffin, Treloar, Mitchel & Omeara 
I think we’ve probably had enough years of just accepting what looks like it can’t be done & its time the club started making things happen. Top mids have changed clubs year after year & its becoming more & more common. We can either continue to hope we get lucky with another Zerrett some time in the next decade of drafts or actively look to control our destiny. You can add to the above list guys like Rockliff & Martin who stayed at their clubs but from all reports were open to other offers.
