I know i'm a bit biased, but i thought i should add someone to your list. Luke Hodge. Can play as a key defender or on a small forward and dominate the entire back line as shown in '08. Can play in the ruck as he did this year for periods of games, and can pinch hit, but i suppose anyone can, although he can't play as a ruckmen for an entire game. Can play as a premier midfielder, and can also go forward and kick goals, although he is more of a kick a goal at a crucial moment sort of guy, not kick a bag of 4 or 5 person. But why would you play him as a key forward when you have Buddy and Roughy.
