I'm quite surprised that no one has mention the St Helens 96 team tbh. We only lost 2 games all year in the league. Wigan away and bradford away (who finished 2nd and 3rd respectively). We won the Challenge cup aswell. And got to the premiership final were we got beat off wigan. Wining 2 trophies out of 3 and only losing 3 games all year is quite some achievement

Is this "Best" or "Most Successfull"?

From a Leeds perspective, I think our 2005 team was our best, though (Due to Senior getting crippled by Bradford a week before the Challenge Cup Final) they only won the WCC.

Stains are light years ahead as the greatest SL team. The first half of SL you had a strong challenge from the Dulls and more recently from us. Trophies won says it all. I think the best team of the SL era was the Stains 2006 outfit.

saints are light years ahead of anyone else as the best.

They've had the best individual team (06)
the most successful single season (06)
and have consistently won more trophies than any other since 96

saints would have to decline into mediucority and leeds or bradford have a continued period of domination for 5 or so years to catch them.

The bradford 03 team is well overrated.

An inexperienced young leeds team coached by daryl powell was within a whisker of that bulls team. How they are considered the best i'll never know.

Over the last several season there has been very little between Saints and Leeds on the field on play - never mind who won the silverware. Both teams have been outstanding with fast open rugby and yes tough defences as well.

In the period when Bradford were at the top there was no real challenger so IMO Saints and Leeds have had it tougher to win anything so maybe it should be these two as equal best.

If not you would have to say Saints by a whisker but close to being overtaken by Leeds.
