I'm not a fan personally. Our PL status was holding back the tide of inevitable declining attendances due to Blackburn becoming a Muslim town and that community not going to games in significant numbers. Thanks to our brilliant strategy in the late 00s of recognising that gate receipts were a meagre fraction of TV money, and therefore we could slash prices to crazy levels with little overall effect on revenue, we were consistently pulling in a lot people from everywhere within a 5-10 mile radius of Blackburn. I remember my uni mate from Bradford even coming to a few games because he couldn't believe he could watch PL football for cheaper than he could watch Bradford City.
And by keeping our attendances up around 24-25,000, it kept the pubs/clubs/butty shops etc in Ewood open. There was also just more buzz about the town generally. In the Big Sam days, there'd be about a hundred of us stood on Rishton platform for the 12:24 train to Blackburn/Mill Hill to get some drinking in before the game. I remember them naming a shot after us in one Mill Hill pub (the "Rishton Rover", tasted terrible but I always bought one anyway
). All of that completely gone now.
Relegation has caused a lot of indirect damage to the whole area in my opinion, that will never be fixed as regaining our PL status for longer than a season at a time now will be nigh on impossible (and even managing 1 PL season is like climbing Everest). Such was the catastrophe of sacking Big Sam, which I'll never get over.
