Personally I would have this as my backline.
1). Dufty.
2). MacDonald.
3). Aitken.
4). Dugan.
5). Milne.
6). Widdop.
7) Hutch.
17) Mann (any back position he can cover).
How nice would it be to have two ball tall strong wingers again (metres down our own end, speed, jumping ability, did I mention speed, intimidation, off loading ability and speed).
I absolutely love Nighty but if picking our best backline I can't see how we can leave the others out.
If forwards do their job and Hutch can control / direct just like a solid halfback then I think you will see the best out of both Widdop and Dufty for ball playing and hole running.
Also with Hutch and Dugan now in the front line our smallest front line defenders would be Aitken / Widdop so not many small bodies across the park.
I actually like our best 17 for next year provided we pick our best 17.
However the only way this will work is if they do everything opposite to what Mary tells them.
If Mary picks teams like he did this year then we will have Lafai, Marketo and Hutch will be dropped by Round 3.
Wouldn't it be nice if there was a competition to Coach the team for a week, I'm in please, couldn't do any worse.
