Any journalist's job is to report the news in an objective, balanced, and fair manner. However, as in any profession, there are a lot of journalists who use their jobs to advance their own personal agenda, which, of course, is unprofessional.
It's clear that Gosselin has a negative bias towards the Cowboys and that bias is reflected in his writing. The power the reader has is to turn a blind eye toward such a lack of professionalism.
It's also a problem with certain sports analysts such as Aikman who goes out of his way to express a negative perspective on the Cowboys. I think he does it in an attempt to appear neutral because of his ties to the Cowboys but he fails utterly. That's why I prefer Darryl Johnston as an analyst because he does his best to be neutral and objective.
Anyway, interesting discussion.
