I wouldn't swap Houghton for any hookers. He is young English and has improved his game massively in the last couple of years. McIllorum is looking good this year, but over the past few years Houghton has been the better hooker, plus he plays for the by the best team in the league, how good would Houghton look in there team (same argument for Briscoe over Charnley). Roby is excellent, but I would guess that he is a lot better paid than Houghton.
We might start to release how good Houghton is, now that he might miss a few games.
