Regardless of the merits of any trades/draft picks the Doggies can get, their statement after the announcement was that Griff was not going anywhere and was a required player, so it doesn't sound like the club are keen. His decision only gives rise to further speculation on those rumours of conflict between players and McCartney, or at the very least some internal issues at the club. Nothing like some ammo to continue giving a rumour some legs...
Who knows? Maybe he's wife wants to move to Sydney? Maybe he does want a change of scenery? But still it's not often a Club Captain ups and leaves like that though. Judd from WCE and Colbert from Geelong are only two that I can think of in relatively recent times.
