Kellaway has played mainly as a wing/FB hybrid anyway, a majority of his tries have come through the midfield so I'm not sure playing him at FB would change his role too much. He played FB all the way through his juniors and his positioning and intelligence seems suited to the role a long with his solid kicking game and link play. Hodge has had his moments, but also issues with positioning at times and under the high ball. With an eye to the WC and the continued development of both Petaia and Wright I think a Koro, Kellaway, Petaia/Wright back 3 would offer more both now and for the future than Hodge.
