You have missed out the rest apart from Pie Warriors' Wire' Stains and (eventually again ) Leeds.
Well St.Helens run at a loss without Mcmanus and friends. Leeds make a profit but have stated they wont be going out and getting big name NRL players as they cant afford them compared to what NRL clubs can offer. Wigan make a profit. Wire are much like Shuddersfield and need Moran and co to survive though Moran is still pretty young compared to Davey for example. Hull was badly run though things allegedly will be better under Pearson. But the fact remains SL is nowhere near as strong as robust as SL RFL and big Nige like to make out. The Championship sees clubs not running up debts chasing a dream they cant live in and the comp is top notch with games unpredictable.
