I wouldn't say centre especially is an area where we're weak, or weakest. We've got Scott and Hall, both SL quality centres, plus Pratt, who for his age and development seemed to just go from strength to strength last season, who I think will just continue to improve and develop. Then Rourke, who seems a good SL quality player with quite a bit of room to improve, has utility value as well and he's very early into his RL full-time development. It's actually an area I think we'll be good in IMO.
Even wing, we've got TJ and Walmsley with Russell as backup, who's a decent SL quality winger, especially as a back up, we can also move Pratt there to play if it comes to it.
I don't think Rourke's got a mention at centre because he played mostly at FB for London didn't he, that's his preferred position and he'll be back up to Jowitt, keeping him on his toes all season.
I think generally we've got good backup for every eventuality, especially as a team just moving back to SL, I think we've got real strength in depth across the park. Every team in SL has areas where they are weaker than others when they scramble to cover if they get injuries, so it's a bit unfair to pick holes in our squad after everyone we've brought in and retained and we haven't even seen them play together yet. It will take some time to gel, especially with a new halfback pairing, centre pairings etc. It's may take a bit of time for us to click but hopefully not too long.
