Maybe it is something to do with the no. of Wigan refs who've joined the senior panel over the last few years and even if it's just subconsciously they don't want to be thought of as favouring Wigan.
I honestly don't think it's that big of an issue because the stats show we're the least penalised team in the league, if we were getting caned every week whilst receiving next to nothing then that would be a different matter.
The job requires them to be impartial in all games. If, for whatever reason, they feel they can't do that, it's an admission that they can't do the job, and so they should step down.
