The simple reality is, there’s only so much hockey they can actually watch. Between the writing they have, interviews, podcasts, general reading they do, etc, there’s only so much time they can spend watching hockey. Then, they’re not just following one team, they’re following the league.
Then a massive trade happens and all these guys need to come out with an opinion almost immediately. They don’t have 2 weeks to research and watch and deep dive into stats.
So they’re forced to spew what base knowledge they have. Some of that base knowledge could be 1 or 2+ years old.
Then you also have a guys who have insider knowledge but clearly lack actual hockey knowledge like Seravalli.
