Rugby league on sky sports why is every (almost) wigan game shown live how do they decide what game to show?

The decision to show all wigan is doing my head in.there are other teams,and no i have nothing against wigan just Dont see why it cant be more even.i havnt seen wakefield live at all,harlequins and crusaders once but we have to see nearly every wigan game i know they are champions but shouldnt each team have a minimum number of live games? Im a bulls fan and weve only been live on sky 3 times
