leeds did it in the 2004 season

Ignore Wigg'n, you are correct.

Hmm...

Leeds in 2004:
=#40BF00Leeds 36-24 Wigan
=#FF0000Wigan 12-12 Leeds
Wigan 26-22 Leeds

=#FF0000St. Helens 56-10 Leeds
=#40BF00St. Helens 19-25 Leeds
Leeds 70-0 St. Helens

Bradford 12-26 Leeds
Leeds 26-18 Bradford
Leeds 40-12 Bradford

I'm talking about the beating each team at least once fact

Whose mentioned anything about just beating each team once ?

Its about going through the entire season and being unbeaten against the big 4 sides in the league, thats beating them all home and away. Before we broke into the so called big 4 those big 4 will have been Leeds, Bradford, Saints and Wigan.

So the question again is as follows.

Have any of those in the previous or present big 4 gone though an entire season by beating the other big 3 home and away ?
