I'm certainly not suggesting he's the most versatile, but if the NAB Cup is anything to go by, we'll see Mitch Hahn given some different roles during the year.
To answer the original question - Pav and Hodge for me.
Paddy Rider gets moved around a bit. He's a player that I'd like to have at the Dogs.

Andrew Embley for me, seems to be able to play a range of positions if asked upon. Can move as small as a midfielder, but still has enough height to trouble larger opponents.
