There was a season recently - was it last season or the first after relegation from the Prem? - where the BUMPER crowd for the WORLD'S BIGGEST DERBY was lower than all but ONE of City's crowds that season and it only scraped above being lower than all of them by about 50. The HDM reported it as a massive crowd yet City's attendance slump was worrying. And I really dont get your point, what 'truthful reporting' do you refer to? And who said anything about them not reporting on City during the closed season? I have no idea why you brought that up, a lack of City coverage at present wasnt mentioned anywhere by anyone.
It's all relative though.
It was a bumper crowd for a RL game in a sport where average attendances are usually below 10k.
At the time City's attendances were worrying falling some 30% or so in a few seasons.
It's not a comparison of the two it's purely two separate (and accurate) articles that people like yourself have interpreted to be some pro-rugby and anti-football agenda.
