Greening (nuff said)
Daics (address our biggest need with the best ever in that role... nice)
Peter McKenna (goal kicking god, would kick bags and take pressure off Cloke, who could then just concentrate on snapping backmen in two in marking contests and creating crumbs for Daics).
Darren Millane (put him on a wing and scare the shit out of the opposition. Also happened to be an absolutely brilliant footballer).
Bucks is my favourite Pie, but I figured that I'd trust my dad's word on Greening, and we have class through our midfield now so having both seems a waste.
I could also see the sense in adding a KPD, maybe Regan. Even though he was 185cm and played a century ago, he was the bloody PRINCE of fullbacks! Deck Reynolds said this about him (thanks Wikipedia):
[H]e made them earn every goal they kicked against him. It was great to see the way in which he shadowed them or marked or punched the ball away, and then, with great dash and a beautiful kick, sent the ball in the right position for an attack. His quick thinking and unruffled style at critical moments made him a star full-back.
Like Matthew Scarlett, only better and not a total flog (he did leave footy to become a lay brother for a while, so that's always a little questionable). Well, that's a slightly unsavoury note to finish on.
Umm... Go Pies!
