If you have to use the abysmal expression "pinchhitter", then Yze should pinchhit at Sandy.
Wheels was tried as a midfielder years ago. The experiment was an abject failure. He is a terrific back pocket and should stay there.
Green was a great forward and should play there again. He would be good for 2-3 goals a game.
Dunn has great potential; could play anywhere, back forward and onball. Same with Bate, although I like him on the half forward line because he presents well.
Would like to see Rivers play up forward occasionally. I really liked it when he occasionally wandered up forward during matches + kicked the odd goal.
