Looking at the team for next season so far we will probably line up something like this:-

Tony
Calderwood
Horne
Yeaman
Raynor
Horne
Dykes
Radford
Berrigan
King
Crocker
Tickle
Washbrook

Cusack
Thackray
Manu
Houghton

So players out of the 17 will be:-

Byrne, Briscoe, Hall, Whiting, Thorman, Dowes, Lee, Burnett and Maloney.

We seem to have enough cover for the backs so IMO I think we need to sign another prop. Signing another centre does not seem a must. Yes we lack a real quality centre to play alongside Yeaman but the only guy out there just now seems to be Talau and I am not sure it is worth it for a year tbh. All that would do is limit the progession of Hall and Briscoe.

Could it also not help their development, seeing another good centre?

i was thinking

tony
calderwood
R horne
yeaman
raynor
thorman
dykes
radford
berrigan
cusack
crocker
tickle
washbrook

thackray
manu
dowes
houghton

Possibly but imo they need gametime. If Briscoe/Hall don't get the games we can't judge them properley. If they get a chance and it does not work out then at least Agar knows that when Byrne goes at the end of the season we need a top centre as the youngsters are not ready. If Briscoe/Hall go really well then we may not need to sign one.

Tony
Calderwood
Hall
Yeaman
Raynor
Horne
Dykes
Dowes
Berrigan
King
Crocker
Tickle
Washbrook

Houghton
Manu
Cusack
Thackray

That would be my team if we had a game tomorrow and everybody was fit.

That team is good enough to challenge for the six.

Only issues with that team are 1) I think Radders will be given a spot and 2) Agar seems to favour Horne over Hall.

Why have you put Horne at centre as they guy is the definition of average and the only reason he got so much praise for last season was due to how low our expections of him are.

put rich horne at centre

Its what I think Agar will do and not what I would do. Agar seems to favour Horne over Hall. I personally would pick Hall and give him some backing. I would also only pick one of Radford/Tickle.
