I understand that the article on ESPN didn't call Tom Brady a pretty boy, like they did in the Daily News, but I don't think that precludes it from being a hit piece.
The author obviously drafted the story to fit his narrative/bias to paint the Patriots organization the way he wanted to paint it.
Immediately after the story Patriots beat writers, former players, and other journalists started tweeting out information contradicting what was in the article. This ranged from Jimmy G having full access to the TB12 facilities and never having contract discussions as stated in the article to no one know what a 'Patriot of the Week' was or others thinking 'Patriot of the Week' was an award for scout team players -- yet still, the article made it a big deal. This makes me believe that either the author did not want to look for evidence that didn't fit his narrative or ignored that evidence when piecing together his article. If you're sensationalizing something to make someone look bad, that seems like a hit piece to me, I'm not sure how else you can look at it. The author's goal was not to inform, it was obvious to influence.
There are also several smaller things that didn't sit right with me about the article. I don't remember seeing one quote on the record in the entire article. I know it's not the end-all-be-all but when journalism is fighting for clicks and not one person will go on record to support your story, that usually says something about what you're writing. Additionally, the author also didn't consult with the ESPN Patriots beat writers, which seems strange for trying to produce a ground breaking piece of journalism.
Usually when a story like this spreads like wildfire, one of two things will happen. The rest of the journalists start piling on (see: Penn State) or it gets widely questioned.
You can just read the following article below to see there's a lot more to the story that ESPN left out because it did not fit it's narrative:
How to process ESPN piece on Pats 'dysfunction'
That's why I think the ESPN story was garbage journalism and a hit piece (despite it not using the words 'pretty boy').
