Whilst Hayne may be 'a' common denominator in this story, you have failed to take into account the other common denominator - sensational stories sell newspapers/clicks.
Don't for a minute forget that the media have a clear understanding that the Parramatta Eels are a team that approx. 5% of the total NSW and QLD population consider their team which means articles/stories relating to the Eels have a far greater reach than most other RL teams. Secondly, Hayne would be perhaps one of the most instantly recognised names in Australian sport, especially over the last 4 years and especially in the Rugby League states. Thirdly, Parramatta supporters are passionate to say the least however in a lot of cases that passion is combined with frustration at having no success in 30+ years and a target demographic that believes what they read and hear from mainstream media.
Put these together and there is no doubt in my mind there is an agenda from the media to find/make up/embellish sensationalised stories related to Jarryd Hayne.
