I liked Chaz and thought he was a decent enough stand off but as Pepe said needed a 7 with him really and the deciding factor for no SL IMO may have been a lack of pace if a gap appeared, that maybe down to the fact the guy had two big knee ops in 2009/2010 so could still come back to him hopefully.
He has a very good short ball at the line, a good long kicking game (as a Widnes fan I forget what a short one looks like) and is pretty solid in defence. Get him a 7 and he'll be a cracking signing for Swinton IMO.
