Wire would be my shout for the next name on the trophy. As realistically it would take about five years of building, Cas for example of last season need o be firstly getting to the upper echelons of the league table , then getting to the semi finals, then getting to the GF (first one probably losing if not more) than finally winning. Whether the new format allows this sort of building we will have to ait and see.

People used to say Leeds were part of a Big Four in the early days of SL. From 1996-2003 what exactly did they achieve? One SL GF loss and one Challenge Cup win.

Warrington have achieved far more in the space of eight years than that Leeds side had.

Both clubs an average of 5th place in the time frames.
Both not won the GF.
Wire have won more Cups but to say they achieved "far more" is stretching it a tad. Especially given that at least part of that 8 years was groundwork for 10 years of success at Leeds afterwards.

Wire have won 3x as many cups and been in twice as many GFs, as well as finish as League Leaders.
That was in the space of 6 years. I'd say that's a pretty good six years.

If we're including beaten GF appearances then we should note the 2 Cup Finals Leeds appeared in and lost too.
I'm not denying its been a good 6 years for Wire. But then it was a good 6 years for Leeds prior to 2004 too.
