I'll take this a step further and introduce my own unpopular sports opinion. I think that MORE athletes should speak up on political and social issues.
I was hinting at that. I like when athletes use their fame to actually say something. Can you imagine if a pro basketball player turned down a Nike deal and then held a press conference over their slave labor tactics in the Far East? It would be awesome.
As you my know, I'm a stathead. And I agree with this paragraph 100%. Now, the hive mentality isn't as bad on the football, soccer, and hockey sides of the metrics revolution, but part of that is due to the nature of the games and the relative newness of their advanced metrics.
Yeah, the early stats are exciting, but after that, the refinement is kind of a waste of time. It's not the precise measurement that matters, but the general concepts. To use hockey, the concept is Possession Matters. Corsi and Fenwick are attempts to measure possession, but at the end of the day, the important thing is that we rate teams on how they possess they puck.
I disagree with you about blogs. I think blogs have dramatically increased the quality of writing. Sure, there's more bad writing than ever, but there's also more GOOD writing. And old sportswriters can't fall back on hackneyed cliches and narratives without being called out. But there's legions of passionate, smart fans writing about the team they love, for no pay. The passion shines through the best blogs. What's funny is the big institutional blogs like Deadspin are oppressively stupid and shallow, but the smallish team oriented blogs can be incredibly smart. The Royals, for some reason, have incredibly smart and interesting writers.
