I'm reacting more to the qualities attributed to him, by people who, presumably, also don't know him. For a large portion of Celtics fans, anything that doesn't suggest they're the best team is considered outrageous. So yeah, I think it goes beyond what would be considered rational response. But to each his own, I suppose.
Except that the issue here wasn't that he didn't think the celtics are the best team. Is that he wrote a column stating with absolute certainty that the celtics would lose to the heat.
So a guy who made a name for himself by being the voice of the boston sports fan (originally the "boston sports guy") suddenly decides to make outlandish claims about the celtics to both pull a "skip bayless" and to gain credibility with fans of other teams. People then call him on it when he is proven completely wrong. There is nothing irrational about that.
He himself does much worse on his twitter account whenever anyone disagrees with him and is proven wrong.
Personally, I think he was once very good, and now is what he used to make fun of. Completely unrelated to what he thinks of the celtics. He used to be a regular guy who made fun of sports writers who thought too highly of themselves, who were part of the overhype machine, and who said outrageous stuff just to get attention. Now he is exactly that.
I share some of your last-paragraph feelings. I think he's too invested in non-writing activities and his brand comes first. Understandably, I think, given all the opportunities he has now and his (seemingly genuine) fascination with celebrity and all those trappings. I have no use for that stuff.
However, you attribute motivations to him in your first paragraph that I would dispute. Perhaps he, like many others, saw this craptastic Celtics team and legitimately thought they'd lose in the first round. It wasn't a CRAZY idea. I don't think you can say with any certainty that he wrote that column as a credibility grab. I've heard that many times round these here parts and I don't find it anymore convincing now than I did then.
Legitimate question: has Simmons wrote a single positive thing about the Celtics this season?
I think people question his motivations because he hasn't tweeted anything positive at all about the Celtics first round win, despite being *very* vocal about other series. The things he has said about Celtics-Heat have been either complimentary of the Heat, or negative toward the Celts.
Legitimate answer: I don't know. He didn't write much on basketball the first few months of the season when the team deserved praise (I know this because I had to suffer through NFL columns and podcasts, neither of which I can tolerate). There hasn't been a lot of positive stuff to write in 2010.
He did do an early-Jan podcast with Bucher and Stein - you could check that.
But again, some people think he doesn't actually like the Celtics and is now biased against them. And others think he loves the Celtics and picks against them for credibility's sake. Both seem bunk to me.
And the twitter thing - I mean, REALLY? The guy could be doing any number of things (like, say, talking to friends on the phone about the C's win, or attending to his family or working). To submit the lack of a tweet, an hour after the game ended, as evidence of anything... man, you've lost me there.
