With Pryce and Eastmond on the move. We will be left with just Lomax and Gaskell ( I think Wheeler is targeted at centre now).
So 2 half backs next year will leave us a little exposed. I think Lance with add experience and cover there. Then after 2 years, Wellens may or may not retire. If he does then Lance will easily slot into the fullback role.
Players get injured, so I can see a Lance Lomax main partnership for 2 years, with Gaskell providing cover and getting the drip feed into the team that Lomax and Gaskell got. Then after 2 years Gaskell will be up for renewal, if he has made it he can step up and take Lances spot and Lance may move to fullback to cover a possible retiring Wellens at that point.
That's the way I would read it. Not a rejection of the young half backs but putting the plan back into place that went out the window with Eastmond and Pryce leaving.
