I very much doubt this gives an indication of Potter's selection thinking ahead of the weekend.

From what I remember, Platt did some training sessions at second row last year and there had been some discussion of him possibly moving inside. Nothing significant came of it though.

To be honest, I don't think his defence is anywhere near good enough to play any closer to the middle.

His defensive mis-reads are much more frequent than his missing one on ones. It's often the case that players like platt are more comfortable defending neareer the ruck as it is more about energy, strength and size and less about footwork and decision making. Sykes was a much better defender nearer the ruck than he was at right centre. Platt is a strong runner so may be suited to second row and if needed I'm sure Potter would play him there. He's clearly not in Potter's plans as anything other than a utility player in an injury crisis and as such you could do a lot worse.
