The initial report was fine and pretty well in line with what you outline.
22 days after that report, he wrote a comically terrible article about how the Blues had shit on Tarasenko and badly misplayed the situation by holding onto him for so long. This article was almost entirely based on
very opinion based quotes,
all of which came from a single anonymous source. To put the timeline into context of the NHL calendar, the article about the trade request broke during the last game of the Stanley Cup Final and the article blasting the Blues for waiting too long to get a deal done was published the day after free agency opened.
I have never seen a more obvious example of a beat writer being used as the mouthpiece for a player agent in my time as a hockey fan.
Basing the premise (and all of the content) of an article on the opinions of a single unnamed source is horrific journalism. If you are writing a "this is how a source feels about an issue" article, it is basic journalistic standard to provide information/feelings from other sources. Whether that is a counterpoint or agreement from other sources in the industry, you need to have something more than the opinions of one person who you decline to identify.
That article didn't resemble journalism or 'reporting.' That was a letter to the editor from the clearly biased source that JR dressed up as an article while removing all identifying info from the source. Allowing a source to fully dictate the content of an opinion piece like that with zero push back or support from any other source is atrocious journalism.
Here is the link to the article. It remains by far the worst thing I've ever read on the Athletic.
