I'm not sure how you can come to that conclusion to be honest. Ronaldo played a handful of games on the wing compared to Xerri playing pretty much a full season in the centres. I like Ronaldo, he'll play Origin in a couple of years and I think he'll be very good for us but he hasn't done much yet to put himself ahead of Xerri. Yes you can argue Xerri needs to work on stuff, but what 18yr doesn't. Ronaldo himself needs to work on alot, namely his ability to control his passion. Suspended for a shoulder charge and sin binned for a headbutt a few weeks later. It's a moot point anyway. Centres will be Xerri and Ramien period ...barring injury. One wants to play left, one wants to play right. Morris on one wing. The fullback and wing spots are dependent on what happens with Moylan and Dugan.
