Way I see it, (Murphy aside being captain) there are only 4 untouchable players on our list, Cripps, Harry McKay, Charlie Curnow and Weitering.
Anyone else on the list is fair game for trade if the price is right.
SOS going by his M.O both at GWS and last year here is keen to try stockpile as many good draft picks as possible, and i can honestly see Graham being touted as surplus to requirements (or he may simply ask to be traded) as a means to to an end to get another good draft pick.
If we had better depth/a stronger list, would Nick Graham honestly be rated a best 22 player ? I don't think SOS is done with the list cull/turnover, put it that way...
