Without appearing racist....
People of Pakistani origin do not go to watch football. In Blackburn there are 35,000 of asian origin, leaving around 50,000 people (men, women and kids) who may or may not choose to go to Ewood. That is less than the capacity of many Premiership grounds. Why then are we surprised at crowds averaging arount 17,000 before we include the away fans? I think it's a bloody good turnout. The fall away from previous years is quite simply fans from out of the area who got bored when we lost the glamour of the Dalglish/Walker days!
Stop moaning... start supporting. Crowds now are similar to any time Rovers have been in the top flight. Crowds in the 30,000 plus region were/are the rare exception to the 17,000-20,000 average that has always been Rovers mean attendence in the top flight.
