I wouldn't know if Matautia is a better centre than Mamo, because I've only seen Mamo play at right centre a couple of times so am therefore unable to compare them.
Similarly, you didn't see Matautia's performances against Hull KR, Leeds and Hull FC this season. If you had, your comparison may be very different!

They both look the part, Holmes is a lot more than just solid and matautia is a proper out and out centre. Both of them seem to have a good attitude and work rate, I think they will fit in well and improve the first team.

As much as I love Mamo he isn't a centre, He has gone alright there and I do think we will miss having him in the squad but matautia looks like a good signing to me.

I’d hope Currie would stay where he was, Holmes is an improvement on Hughes, but Currie is ahead of him IMO, so should stay in his favoured spot.

I agree Currie should stay where he is alongside King and put Holmes on the right presumably with his pal Mata'utia as a pair that know each other?

I know that it is going against the current trend of selecting an extra prop at 13, but with his handling skills and speed, I think that Currie would make a superb "Old Fashion" Loose Forward.

A good option as my choice was based on a presumption of Hughes at 13 utilising Currie's running skills out wide a straight swap Hughes for Clark.

I suppose it also depends on the continued development of our young centres and back rowers?
