What do you expect from a new team? It'll take time for them to get a hardcore fanbase, as I'm sure it does any new team.
I've never really bought all this anti-Wigan stuff. Yes they don't sell out their home games every week, but so what (and they would be if they only had, say, a small 12,000 seater stadium). They've proved year after year now that they are one of the top twenty sides in the country (although whether or not that still remains to be the case after this season is of course yet to be seen).
