Williams and Hampshire are two of the most promising half backs I've seen in schoolboy and junior football and did a great job individually and as a partnership in the Wigan academy.
They should have been developed and moulded into a partnership for senior football. One is now a hooker/half and the other is a full back despite never having played there as a junior.The game is crying out for quality English half backs..it seems to me that the Wigan management can't see a good thing when it's staring them in the eye but sadly maybe it's symptomatic of the game in general.

He gets a mention in the full article : “I did the same with Lewis Tierney, and he knows what he needs to do. But Rocky can play in the halves, Lewis played on the wing against Salford – and played really well.”

The one who doesn't get a mention is Logan.

At the last fans forum Rads said they were looking to agree new deals with Hampshire, Sarginson and Charnley very soon. I've not seen any new deals announced since for any of the three.
Should any of them leave, or two out of the three, then keeping Tierney and Thornley would become essential.

Players may leave due to Sam's arrival but I'd be looking elsewhere.
Bowen and Burgess are going/gone! Patrick is on a loan deal and needs to be very convincing very soon if he is to stay. Hughes and Burke are out on loan, their return isn't guaranteed.
That's five players of which only one is a regular first teamer now.

A lot of Rugby to be played yet and some may surprise.
Sam Tomins will be fitted under the salary cap, you can bet on that with IL!

We have a partnership with Workington Town but we don't seem to be using it as much this year. Manfredi has played there a few times this season and when he went straight in to the first team he hasn't looked back. Tierney has played there spasmodically which isn't doing him or Town any good. Gildart played for Town last week and now he's gone on loan to Salford. Same with Greenwood, couple of games up there and also on loan at Salford. Other clubs are getting these players for at least a month at a time but our partners don't know from one week to the next if or who they will be getting. Doesn't seem right!!

The only one I'd keep from the potential departures you mention is Greg Burke.

Sam Hopkins is another who will probably leave. He'll be on a modest wage you'd think but it'll create a bit more room.

Lenagan has already stated that his arrival isn't dependant on the marquee player rule although he has stated it would help. We can't be too greedy but another big prop would be handy but if Sam's the only signing then so be it.
