One thing an extended period outside of the top flight does to a team is it sorts out the true fans from the fickle ones!
I was a part of the 1200 that turned up week in week out getting beat by clear 50/60pts a game. I travelled home and away come rain or shine to watch Hull KR take some of the biggest beatings and also some of the most entertaining rugby i've seen in or out of the Super League.
It is fans like the original poster that clubs will lose once the team goes out of the top flight (doubt that would ever happen to you guys though). I have had to get to games upto two hours earlier just to get my spot in our East stand since we got promotion all because "fans" like these want to come and watch a successful team. Yes their money their choice also their money keeps success coming to a club and without our rise of about 600% since our promotion year we wouldnt have finished 4th last year and probably be back in the second tier by now.
Just remember though you true supporters, Leeds are one of the biggest names in World Rugby League and a few defeats at the start of a season is no reflection on how you will finish come September.
