What do you expect him to do? Especially from the wing? He's down on confidence for sure, he's not backing his ability like he used to. However he's still running into the middle of the field to get involved. He's certainly not trying to be lazy or a passenger by any means which a lot of people seem to be implying. He needs to lose weight for sure. However a lack of confidence is his issue at moment. Aku is a confidence player, and when he's down on confidence he's down on form. It's always been the case.
He definetly needs to lose weight, but more than that he needs to get his confidence back...and he's not going to get that back being dropped to NSW cup. It will do the opposite. You drop players to NSW cup to give them a wake up call when they're not putting in. Aku is putting in. He's just not doing it with his usual confidence and spark. The only way he's going to get that confidence back is by the coach showing faith in him and keeping him in the top grade. No doubt he needs to lose weight, but he can just as easily do that playing firstgrade as he would playing NSW cup.
