While I don't mind the changes, I would have prefered Astbury for Grimes as the only change. Whitey will give us a speed boost on the big Darwin ground and he has been ok all season so I understand him coming back in, but we look a bit less balanced in the backline without someone playing Grimes 3rd man in role.
I also understand bringing Miller back in. He has been important in the games he played and we are better in the short term with him in ahead of Post, but we haven't been doing too badly by giving the kids a go and taking that longer term view. Would have liked to see how Post went second game in.
Miller might get another mysterious virus and post comes bac in.
