As stated above the odds were always stacked in the Super League teams favour. NRL teams would come in cold whilst the SL teams already had 2-3 regular games to be match fit. There is nothing in this world that gets you match fit apart from playing in real contests. Also have to remember that NRL teams would often treat the WCC as an inconvenient distraction and send B grade teams...Wasn't the old format pretty much always played in England during their season but our offseason(pretty much a trial)?
Not taking away the wins but odds were stacked in favour of the ESL clubs
