I don't agree with how he's usually characterized here. He's definitely pro-team and anti-whiney-fans, but he's got plenty of things he doesn't like about how things are run. Whenever one of them comes up, I'm surprised at how many think it's an exception to the rule for some reason.
But his writing style is really annoying. Not a fan of the folksy way he likes to make his points, and not a fan of constantly asking questions and then answering them. Even the language he uses makes me cringe sometimes. A little bit of that is ok, but then a little goes a long way and a lot is way too much.
I don't think he's a jerk as much as he is Italian. He just likes to holler and argue a lot.
