Leeds are the most successful Rugby League side in Super League History so therefore answers the question. Leeds have been truly outstanding in the play offs since 2007 with only 2010 being there only non apperance in the Grand Final.

Thank you, some reality at last. Before people harp on about the Dad's Army Rhinos team they should check the age of Hardaker, Watkins, BJB and Hall. Good YOUNG players with their best years to come. I conveniently (for the sake of my point) won't mention our, ahem, forwards.

I think the best 3 teams in SL history are 2003 Bulls, 2004 Rhinos and 2006 Saints. Impossible to choose between them.

I would modify that slightly because although Bulls and Rhinos were close they weren't quite to the same level as 2006 Saints. Had they been, they too would have swept the board trophy-wise in their respective seasons and done so with so few losses on the way.

The Bradford team did sweep the board in 2003.

The Leeds Rhinos team of 2004 lost just 2 Super League games all season and won the GF. They lost to us in the cup when we beat Bradford, Leeds, Hull, Huddersfield and Wigan to win it.

I don't think RL history is her strong point!!!

I've just said on Red Vee that no team has won the treble, or the Challenge Cup / Super League double under the latest system.

Is that the team or the system?

Did they? I didn't realise they'd done the treble. Fair enough. That means Bradford 2003 and Saints 2006 would be the best teams in Superleague so far.
