Experienced prop - someone like Dowes, or even Fozzard as wouldn't need to be a starter.
Centre - Dean & Isa are pretty good signing sbut one more would be great, i'd still go for Gleeson tbh.
Stand off / Scrum Half - Hanbury can play the other, Tim Smith gone very quiet bar more Wakey talk so who knows.
Hooker / Back rower - If we get another half back we have Clarke, White & Coyle which wouldn't be too bad. If we do get Scott Moore i'd play him 13 in a fully fit side with the obvious option of him playing hooker should we lose someone their or at half back (White to cover).
Winger - We only really have Flynn and Ah Van so i'd like us to sign an option with real burning pace, someone like Amos Roberts should he recover from knee operation.
That would give us 24 first team players (excluding Owens & Gilmour who you'd only be looking at a handful of games at most) so probably still 2/3 short but wouldn't need to be considered SL starters as such or maybe someone like Glenn Morrison who would do a good job for a season as Haggerty & Leuluai develop physically a bit more.
