Yes ... and that's the point. Coll v Rich (while both are flying) would get that crowd and ratings at any time during the season, including the depths of Winter - so why waste such a top drawing game to open the season with. On the other hand, Carlton can only draw a massive crowd on round 1 - and that's it for them.... Call me crazy but I reckon Collingwood or Melbourne vs Richmond would generate a lot more hype than Carlton. But hey they got a massive crowd last year and no doubt millions watched it on TV (as opposed to all the other games of footy on offer) so why would they change?
So it all makes sense. Don't waste top games on round 1, save them for later, and give Carlton it's one and only chance at a really high drawing game (until they eventually come good at some stage in the hopefully distant future)
