Jake Carlisle would go #1, not even up for discussion. Players who can play exceptional football both in defense and up forward are extremely rare, Pavlich is the only other player still playing who could do it.
Except for Ben Reid and Harry Taylor as two other examples (off the top of my head) who are excellent defenders but have also shown they can play in the forward line to great effect. Not knocking Carlisle - he looks like becoming a very good player - but his ability to play at either end isn't as unusual as you are suggesting.
