In a tough decision, I went for Murphy. Mainly due to the fact that he is (I think) the youngest of the players listed, but still looks to have the 'champion' about him.
His versatility seems better than the others listed also. ie, back, center and forward line seem all just as comfortable for him.
I would rate them in this order:
1. Murphy - as I stated above and the fact that he is virtually a baby himself, but also a ready made draft pick.
2. Stevens - One of the best midfielders going around, plays with the best, and is a position we need back up in.
3. Brown - As JF said, very damaging on his day and can play on the ball as well as up forward.
4. Power - a top class player but very short. Here's me hoping McGrath and Krakeour can be the Power of Richmond in the future.
5. Wirrupunda - coz he's black and we know what he can do.
