Quote: Marky G "got to be sinfield surely'"
Probably will be, but Hanley deserves special mention. His skills were completely different to Sinfield, but he will be on the list and should be a very strong contender for nothing other than his World Record 44 Tries in a season for a forward, which I think he shares with one of Ray Batten or (more likely) Bob Haigh.
Then there's Dave Heron too, but that's another discussion...
