If he stays, get him to tag. God knows we need someone to play that role, it may as well be him
Can't do that, play him in his best position
Seriously though...
Seeing that when they used him as a tagger in the Freo game for the 1st half; he kept Serpng incredibly quiet it would appear to be a no brainer. For reasons only the coaches can expain 2nd half we dropped the tag and Serong cut us to ribbons.
IMHO when he tags, he nullifies his opponent and then gets the pill himself, increasing his numbers and impact
