How would that solve anything? The big clubs would sell out to tourists and the prawn sandwich brigade if nobody who lived within 50 miles of them went to games, and even if in the long run ticket sales suffered they get hundreds of millions from TV rights and European competition. The only thing fans staying away would do is kill football below the Prem and convince a lot of owners to walk away for good.
I think the depth of feeling over the Super League caught owners by surprise and they weren't ready to win the PR battle on short notice but was it to come up again in a year or two, I have no doubt it would succeed this time. Just look at what is going on at Man U and Spurs in the last few days, the fans don't matter in the slightest to these owners. Anyone who thinks the common fan has any say (at least outside of Germany) is clinging to nostalgia.
