I think it's worth looking at 'something' like this for a bit of mature coverage. I haven't followed Membrey close enough in recent years to know if he is up to it, but I agree with the thinking behind looking at someone like him in the short term. With Lewis out our key position forward depth is non existent. Battle will help a lot as gives us a bit of flexibility, such as throwing himself or Sicily forward, but another one, someone like Membrey, who can at least fill in if injury to Dear or Choll occurs in would be useful. Scaife hopefully might be that player but is still so young. Good sides have that depth. Look at Brisbane, they wanted Ryan from us just for depth for their tall forwards even though theirs are stronger than ours.
I wouldn't do it. I don't think Membrey is a good fit. Getting on too. Unless Sam Mitchell is thinking Stuart Dew. Anyway, the way I look at the forward line is that Gunners most likely retires but we pick up Battle and have Serong too. Frees up Weddle who moves forward and plays the third tall taking Gunners spot. Weddle can play anywhere and there is midfield, wing etc. but I think we have plenty of fat in those positions.
