Yeah im thinking they are using different metrics, like run metres, win percentages, trys accumulated etc, not the bold stats of GFs played win etc, coz Realistically parra made heaps of GFs but they were terrible in that same timeframe, doesn't mean they were a success..
And minor premierships no one cares about, unless you're a soccer fan, then they mean the world...
I do however agree storm are the most successful side in the NRL era, although roosters and now panthers are also up there too... (as for GFs storm are on 4 in the NRL era.... we can't count breach years, which says a lot about why they were so successful, the lesson being "you cant keep them all")
NRL dont need perfh, they need more players or another area that can produce more players like Qld do, like western sydney does, like new Zealand can, then you can start plonking teams in perfh, adelaide and geelong if you wanted to
