If Michael Cheika can get the Wallabies -the f**king WALLABIES, who have sucked ever since John Eales retired - to a RWC Final, I've no doubt he can get a perennially under-achieving NRL club, like the Eels, some much-needed on-field success.
I stated it before, and it was glossed over, but the point is still valid - rugby union, though boring, is a technically much more difficult game to master, than rugby league.
I see no reason why a man who was so successful in union, cannot translate that to league.
