The back row looks very strong, respectable even by SL standard. The backline looks solid and Jimmy has followed the adage, if in doubt make sure they're big enough.
Gaskell is our one known quantity at half back but good luck to Harry S. You can't sign quality scrum halves when you've just been relegated. It's up to Jimmy and co to make a player out of him.
My concern is this set of props,
Adam Sidlow
Dan Flemming
Mark Offerdahl
Karl Davies
Paul Clough
Samir Tahraoui
Sam Bates
With O'B, Halafifi and Conroy as three very young hookers. No doubt they'll do well in the Championship but come the play off games if both Sidlow and Clough are fit then two of Offerdhal, Davies, Tahroui, Fleming will have to demonstrate they are SL level players. I trust Lowes and we're in the boat we're in, but it's a significant set of 'ifs'.
