Plenty of people. He's mocked for his voice, his face, his podcasts, and his thin skin because SJH decided to take out a douche stick in 2004 and whack him over the head with it a few times. He gets way more heat from people on this site for a very specific reason. And it's stupid.
Doesn't every writer on this site get some amount of shit?
Joe Posnanski is a much better writer than Simmons ever could dream of being and cranks out quality pieces day after day after day all while writing a book every two years. But a lot of people (myself included) felt that he dropped the ball with the Paterno thing and ripped him.
Bob Ryan is a writing god as far as I'm concerned and there are folks here who don't like him.
When Peter Gammons wrote more, people around here used to rip his stuff apart on the regular. Gammons has done more for journalism than Bill Simmons could ever think of.
Like him or not, Peter King is a prodigious writer who is probably the most plugged-in NFL writer right now. He writes a crap ton, is on TV a lot, writes books and is the editor of his own web site. We have an entire thread devoted to crapping on him.
Even someone who is practically universally reviled on this board: the ubiquitous Dan Shaughnessy (who you have to admit can turn a phrase and knows which buttons to push) gets a lot of shit (deservedly or not).
I would argue that the five people I listed above have done more (or just as much) in their respective fields as Simmons and they all get slammed. That's partly what this site is about: to talk about media folks. And the fact that you're arguing that Simmons should only be spoken in reverential tones is pretty rich, considering how Simmons came to be renowned back in the day. His links were daily body slams on the likes of ancient, lazy dinosaurs writing the same things day after day after day. You could argue that Bill Simmons is the father of this very media board.
Answer me this: why should Bill Simmons be any different? And what is the "very specific reason" for Simmons getting more heat from people on this site?
