It's a number of things:
Not as good to watch
The blanket means that as a spectacle the game isn't as good. I don't care what anyone says, but this business of passing the ball around in an arc around the 50 is not as good to watch as quick ball into a the full forward line, with guys like Mickey Linden, Marsden, Canavan and McDonnell out in front of their marker and taking on their men. We just don't see as much of this in today's game as 2001.
Perception and negativity
Why would I be bothered going to games if the so-called experts keep telling me that the product is rubbish. Notwithstanding what I have said above, I still get a kick out of watching football and we still have some fantastic games, but when the very pundits that you would expect to be promoting the game on TV are saying that every game is shite, it's little wonder attendances are falling. The amount of negativity surrounding the games is at an all time high and it is now in vogue at all levels, from pundits down to club level, to criticise county football.
Hammerings
In 2001 there were some hammerings, but I don't think there were so many as there are now. Leinster was competitive. Ulster, despite the fact that two teams dominated from 1999 to 2010, was still competitive. Dublin matches now literally aren't worth watching until they reach the Semi-Final or Final. They are playing at a professional level.
Over Exposure
I remember thinking that with so many games televised and so much coverage back around 04, that supporters would lap it up for a while, but that eventually people would take it for granted and less would do them. Take the first Ulster Final that went to HQ in 2004. There was 60,000 there. Only 30,000 for the Ulster Final Replay in '05. The qualifier effect was alive and well, with Sligo, Fermanagh, Limerick, Derry, Donegal getting good runs. There were loads of novel pairings - I remember Sligo and Kildare I think attracting a great crowd on a Saturday night around '04.
Half Empty Stadiums
There is rarely a decent atmosphere in a half-full Croke Park. It looks terrible on TV and exacerbates the notion that we have a poor product. I cannot understand organisers taking smallish games to big stadiums. Better to have a small ground filled to capacity, because the atmosphere is all part of the product.
