I'm happy Niu is staying, you can see the potential there. I think he is already quite good in attack and will likely only get better. His massive issue is defense, whether it be centre or fullback, hopefully Kevvie and his team see that and are addressing it because if he can fix that part of his game, there is a LOT to like.
It also creates competition for spots with Cobbo as well, hopefully one of them really take the bronco by the stirrups and show how bad they want it. Cobbo could even develop as a winger or centre as I think he is a bit Gagai like in how he plays, could play any backline position really.
