LMS is a talent and it's easy to bag him by saying he's had it easy or is overhyped by his team but he's still a good young prop playing in a poor squad.
If you don't rate LMS then sadly there's not much better out there.
We may have to start looking at other players who can switch.
The first guy i'd be looking at is Langley. He's got the size, strength and attitude to be a quality prop IMO. I'd liken him to Coley in that he's a unit with a real motor inside who just with his sheer natural bulk and strength will be able to adapt easily to the props role.
I also like the look of Watts at Hull KR as he's another big guy with a lot of potential and like Mossop he could move to prop.
