WTF?
Hams is wayyyy to small to play in the middle. He does well in the WAFL because of the sizeable different in body sizes compared to AFL mids. Can you imagine how he's go against Dal Santo, Hayes Montagna and Jones? He wouldnt get near the ball
He is lacking in height, not size. I believe he would be able to hold his own against those guys, he is a little ball of muscle.
It probably won't happen regardless.
