I do think Ryan Hudson hasn't been his old self this season, so thats a possible. But with Orr, Clarke and Milner in the squad, I am less worried about this.
I think the only others for discussion would be Isa, Fozzard and Widders;
Isa looks a great prospect, but if he cant get fit and on the field, thats unfortunate.
Widders and Fozzard have to figure out if they can go on again and up their levels.
Not sure why Mathers attracts so much criticism! I am comfortable, relatively speaking with 3 fullback options in the squad.
So, looking at this season I would suggest that with Thompson, Eden and Arundel having shown well, that 1 outside back and look at the grunts - I think Parker could fix one of those spots for us, Davies seemingly will be back at Wigan. Snitch seems to be on the wrong side of TM somewhat, but the new coach effect will negate that.
If you look at our pack with Walker and Huby back in it, then we need to add depth, not have a wholesale clearout.
We put ourselves in a position for next season, by playing Clarke, Milner, Holmes, Davies, Eden, Arundel etc to NOT have to make wholesale changes to the spine of the team and ADD to the squad.
