Crichton has played fullback for Panthers before and was woeful. Worse than Taaffe
Which games did you watch? I saw Crichton play a few games at full back for Penrith, and he was adequate without being inspirational. This was pretty much what I would have expected from a very talented player being asked to help the team out in an unfamiliar position.
I have absolutely no doubt Critta will be a very good full back if Ciro plays him there. Having said that, I would leave him at centre. When we signed him, we were desperate for a quality full back, and nobody had heard of Joash Papali. We now have a player who is probably not quite ready to play first grade, but who is on track to be the best in the competition when he is.
