My opinion, and hopes is that he will stay, but if he doesn't, then its not the end of the world, because we will get a ****load in return, no doubting that.
Just quickly of the top of my head what I'd expect from each club.
Carlton - can't think of anything, they wouldn't be involved unless they managed to get draft picks 1,2,3 and 4.
Collingwood - Didak is a must - he along with Judd i rate as my top 5 prospects of the game (other three are riewoldt, pavlich and Jon Brown). But I would expect we could bargain for even more than Didak as well. Perhaps even get a good tall in there.
Essendon - I reckon Matty Lloyd (still only 25) or Adam Ramanuaskas or Mark Johnson along with one of their young key defenders (Jacobs??) plus draft picks.
Geelong - Joel Corey plus plus plus (not sure who else).
Hawthorn - Jon Hay (depending on his 2003) plus Luke Hodge.
Melbourne - Nothing too interesting here.
North - Daniel Wells plus Digby Morrell plus very early draft pick.
Richmond - Ottens plus others.
St Kilda - Goddard or Ball or Riewoldt plus others.
Bulldogs - Nothing too interesting here.
The main clubs I reckon we'd deal with would be Colingwood, Essendon, Hawthorn (mainly cause of Luke Hodge), North Melbourne and St Kilda.
But in saying that I'd rather him stick around here.
