Or a Question why have most clubs in the red rose county play out of better stadia?

Just remind me what St Helens have won in the last three years again old lad. Before we know it we'll have Hunslet fans banging on about when they won all 4 trophies. Leeds are the biggest club in Rugby League, just ask Alex Murphy, one of your own.

OK, lets put it another way when was the last time Leeds won the Challenge Cup, League Leaders, Superleague in the same season and the World Cup Champions following it. That is what I call Rugby League dominance as opposed to Superleague dominance.
Yes, Leeds are the biggest club in rugby league for winning superleague whichever format is thrown at them, we cannot dispute that. But rugby league is more than that in the professional era of the past, present or future.
Also does it matter when a club achieves success it doesn't devalue. Its likes saying a club who has won the 1st 7 years of superleague has lesser value than a club who have won it the last 6 years.

Yorkshire teams this season have won the SL championship, the WCC, the Championship title, the Championship 1 title and League leaders shield and provided both finalists for the National Rail Cup. We also has the Championship league leaders shkield winners. For this season, at least, Yorkshire are the biggest RL region.

The lack of any good football in the Yorkshire region is probably a good reason for there being more interest and pride in Yorkshire RL.

Outside of Wigan, St Helens, Warrington and Widnes, interest in Rugby League is pretty much non-existant west of the Pennines, which isn't helped by having 4 of the most famous and successful English football clubs in the area.

RL in the Manchester area for example is dying on its , a combination of poor sides, successful football clubs and also a huge change in the ethnic set up of those communities.
