I think the issue behind all this is Demetriou looking at how to get the currently strong teams (Geelong, Bulldogs, Hawthorn) who don't have big matches into a blockbuster without having too many 'blockbusters' per year, and he sees QB as an opportunity to have, say, Hawthorn vs Collingwood, which this year in round 7 drew 76,048 without being a 'blockbuster'.
However I think this could do us a favour of sorts: getting people to turn up on Monday to prove him wrong. I guess it's possible that he came out and said this to purposely boost the crowd numbers on Monday.
