Whilst its great to speculate about 2013, big decisions still have to be made (announced) about the cornerstones of the 2012 Rovers pack, in particular Galea, Clinton and Lovegrove, but do we really need to retain/replace them?
I will be very surprised if Clinton is retained (even though he is one of CS's bue-eyed boys, the financial package is a major stumbling block), but with props Paea, Taylor, O'hara, Green, Beaumont and a rejuvenated Netherton signed up for 2013, and if Rovers retain the promising Ofori and Esselmont, then I don't think we need a new signing.
The 2nd row is a different proposition, take Galea out and there is a distinct lack of depth. Signed up are Mika, Horne and Cox (plus Griffin) with another of CS's hopefuls Ollett (OOC). If Galea leaves and isn't replaced IMO CS will have to redefine the 12 shirt role. TBH I favour a strong running forward like Coxy but he will probably need 2013 to get back to his 2011 level. CS has been experimenting with Josh H in the 2nd row so he adds cover. IMO, there is a strong argument to retain Galea and give the likes of Cox, Griffin and Ollett time to develop and then make a decision for 2014 season. On the other hand, CS can bring forward that decision by going with what he has already got.
The main problem is at loose forward or the 3rd prop position. Lovegrove has taken ownership of this shirt and will be a major loss to that role. Murrell has been coming off the bench to support Lovegrove but his mobility is a concern, although he seems to have found his form in this role. The back-up is thin on SL experience with only Petersen 'blooded' but again CS rates him. In the reserves Tyler Hepi has been filling this role. IMO Blake Green or Craig Hall could do a job, but that would mean redefining the role which might not sit with CS's strategy. IMO, the loss of Lovegrove would be massive but there are exciting options open to CS.
In conclusion, then, Rovers don't necessarily need to replace Clinton, Galea or Lovegrove. All three players can be absorbed (the same applies to Webbo ie Salter) because of the depth and options within the squad signed up for 2013.
Having said this I do hope Rovers retain the services of Galea and Lovegrove.
