So, I don't know just what mistake you're referring to. If you have a link I'd appreciate it.
But people, even reporters, are allowed to make mistakes.
But your whole post really seems like you don't know who Westhead is, or his body or work. He's not some social media muckraker. A lot of his stories have been deep investigative dives into allegations of sexual abuse in NHL clubs, trouble within Canada Soccer, or corruption within minor hockey in Toronto. He's TSN's "senior correspondent". He doesn't post daily, but rather only every couple of weeks.
If he, I dunno, said that Glendale was east of Phoenix, instead of west, I really don't think that detracts from his reporting in the slightest.
