It will be interesting which side they play Cotric on. I have never been a big fan of right hand ball carriers playing on the left side. They seem pretty ineffective. If you look at most of the good centres they play on the side of the field that represents their dominant hand.
Guys like Lattrell, Inglis, Gidley, Gasnier, Crichton, Lyon, J Moz, etc all played on there preferred side. I remember watching J Moz in origin play right centre and even though he defended well he was no threat in attack. I cant think of too many really good left sided centres who carried the ball in their right hand and vice versa. They cant use a fend and are normally cannon fodder.
The only half decent one I can think of is Jennings but he was on the elephant juice.
Personally I would play Hoppa at left centre and Cotric at right. Hoppa aint a threat on either side so at least put Cotric on his preferred side. I noticed this year Cotric played right wing for Canberra. In his other years he was left wing and Rapana was right but even when Rapana came back this year Cotric stayed on the right.
