My 17 for next season would be

Johnson
Penny
Atkins
Ratchford (Evans as ratchford is supposedly out injured)
Lineham
Gidley
Sandow
Hill
Clark
Sims
Currie
Westwood
Westerman

Dwyer
Bailey
Dodds (cox as dodds is out injured)
Hughes

So who are injured and won't be ready for the first game?
Ben H, Ratch and Dodds ?

In which case I think our line up against Leeds will be

Russell
Penny
Atkins
Evans
Lineham
Gidley
Sandow
Hill
Clark
Sims
Currie
Hughes
Westerman

Dwyer
G King
Westwood
Bailey (although this depends on how fit he gets and whether TS thinks he'd need to him to make a statement for his future especially against his old club - but Laithwaite and Ben Evans are in with a shout).

after reading input from people that know their stuff, Gidley has to play FB for me.

16 Westerman
17 Evans / Laithwaite / King / Bailey / Harrison (when fit)

Smith is fortunate that Gidley can play full back his favoured position and stand off and I would like to see him at full back, Ratchford will probably miss the start of the season even so I don't see him as a play making stand off, rather better suited to but then again I'm not a coach or Tony Smith.

I'm guessing Smith will go with what he has available and play Gidley at six, I'm also hoping Patton comes through at some point next season, whatever happens selection between 1/3/6 should be interesting.
