And they're also the dim bulbs who think because Hayes is big, doesn't score at an elite level, and is used sometimes on the PK he must be a good defensive center. When in fact he...isn't. I saw one of the fellows, perhaps the Jamie guy, tweeting about his "solid defense" or whatever last week.
Hockey is a really hard sport to analyze casually even when you watch a lot of it. Unlike our other popular sports, it isn't a series of esily digestible sequences with natural stop/start points (even basketball rarely runs more than a minute of clock without play resetting from scratch) where some analyst who can hammer into your head what you just saw with a dozen replays. You need to be good at kinda indexing player actions throughout a game in different situations and knowing whether they were the right action to take.
A lot of people can't do that—either don't have the attention or don't actually know what the correct action usually is—and end up just developing notions about players based on the archetype and then letting the most glaring examples stand as proof. So Ghost is "offensive d-man who can't defend!" and they note the 2 times he gets pushed off the puck in a corner each game—perhaps they result in a big save or even occasionally a goal against—but ignore the 14 times he successfully got the puck out of the zone on his own and avoided a prolonged opponent possession entirely. Or Hayes, they'll remember a handful of shorthanded goals, but not a mountain of missed assignments and poor reads.
