A lot will depend on injuries, as with a full strength squad I can't see us struggling at all. Whilst losing Graham is the biggest blow, I don't think it will be catastrophic if we can keep all of our props fit. If Wheeler could manage to stay fit, that would also make a huge difference in our attacking ability and pace.
A fully fit side such as this
Lomax
Makinson
Shenton
Meli
Foster
Wheeler
Hohaia
Puletua
Roby
Perry
Soliola
Flanaghan
Wilkin
LMS
Laffranchi
Flannery
Clough
With options such as Gaskell, Wellens, Magennis, Ashurst, Dixon, Ashe, Moore and Gardner (if the last 2 are still around) makes us one of the strongest teams in the league. Again, the biggest factors will be injuries and how far the young players develop.
