I'm old enough to remember this. It's a bit unfair to compare performances. In 96 RU had only had a year of professionalism and it showed up against a really great RL side in Wigan. I suspect it would be quite a different match up these days as top RU clubs have learned all those hard RL lessons on defensive alignment, running lines etc
Indeed St Helens and Sale did the same years later - Sale won, albeit it was closer.
