The Kikau issue if more of a Burton issue imo. Burton just doesn't have a clue how to use someone like Kikau who is more finesse than pure power these days. Kikau can do it all as backrower but if the bloke inside him is getting it wrong then Kikau just isn't going to do much.
I prefer Preston on the left edge over Kikau if we're going to stick with Burton (and he doesn't develop enough as a ballplayer), Preston is in the Cooper/Hoffman mould where he's just going to consistently run strong, well angled runs for 80 minutes. Having someone like this outside Burton makes things a lot simpler for him and should force him to play a lot more direct.
Anyway I don't know anything, the great Gus knows it all aye. Not allowed to have any real opinions on here anymore
