There's a chance that can happen I suppose, but I personally don't think they have signed him as a centre. I'll be surprised if he is their first choice as 3 or 4. They are looking for someone to fill that bench role to play in the middle and add some creativity, much like his role for us. They don't have much spark at 9, so they are probably looking for something to fill that void.
If he was still capable of playing centre then he'd be doing it for us. I recall him filling in there a couple of times last year during games when there were injuries, and it was decidedly underwhelming. If he still had some game then he would have been ahead of Burbo and Harper you would think. Des doesn't see it, neither do I.
