I don't think its a huge rebuild needed but we have some areas needing to be strengthened:
Full back - I think Holmes is good there as an option but I prefer him in the halves. Jowitt can play there too but if we could get someone like a Matty Marsh or even Jamie Shaul I'd be very happy.
Wingers - I'd like to see us try and get Jorge Tuafoa for another year. Think with him and Blackmore as our wingers for the full season would be massive. If not, could we tempt someone like Jermaine McGilvery over for one last year (injuries permitting). Add in another back up option too
I think we are good at Centre - Gill and Myers would be my first choice next year with Arundel as back up, maybe need one more as cover (maybe a wing/centre option).
Half back even if Patton leaves I think we are at our strongest here with Holmes, Gaskell, Lilley, Lawford and Jowett.
Props again we may need an extra one with Fenton unlikely to get another year on loan and Baldwinson to come back from injury. Lawrence is another year older but looks like he will go another year and alongside Scurr, Doro and Matongo this would be a good starting platform. Could someone like Scott Taylor or Liam Watts be an option?
Lilley needs to be in the hooker role next year for me and back up to half back. I don't expect GFS to play that many games so this leaves us one short. I think James Segeyaro has been great when he has come in but seems like he is not staying next year which is a real shame. I think Adam O'Brien might be too similar to Lilley in that role so would he bring the impact needed (or visa versa?)... don't see too many other options though.
Back row is where I'd like to see us really strengthen. Brad England and Chester Butler seem to be signed on for next year and hopefully Appo will follow too but if we are to push for a title tilt we need to be aiming higher than this. Ben Helliwell, Luis Johnson and Alex Sutcliffe are all off contract and would be good options to consider for me. Baitieri for another year would be a good shout. I think we are 2-3 light in this area.
