Quote Wheels="Wheels"Didn't Bradford do it in 1997?
IIRC only a 22-22 draw with London Broncos prevented them from a perfect season.'"
No that never happened.
I don't have access to the records at the minute but no SL side has gone through a regular season undefeated.
In Bradford's case in '97 I remember them getting beat by Wigan at Odsal, possibly second to last round. I think they perhaps lost the final round also.
Of course it also depends what you include as that was the season of the ill-conceived World Club Championship where the SL teams recorded very few victories between them, Bradford amongst them who were undefeated domestically that season at the time.
