The article is amusing but as others have pointed out he's hopelessly pessimistic about KG's knee.
I also think he needs to get off Kevin Durant's lap - so to speak - at least a little. He has some really wild expectations for Durant. Don't get me wrong, I think he'll be good, but I see Kevin Durant as a potential Carmelo Anthony kinda guy, not the next MJ or even LBJ (read any of the recent articles about how poor in terms of +/- Kevin Durant has been in his first two years of play).
I'd love to believe Simmons at least insofar as the Spurs going to the Finals. I have to believe, however, that we will get there too, and then beat them.
To the people arguing about whether Simmons is a journalist or a blogger or whatever: I think you just need to view him as a guy with a lot of sports and popular culture knowledge who writes in a fairly sophomoric and often somewhat tongue-in-cheek manner. Yeah, he stands firmly by the opinions he writes, but I think he tacitly acknowledges that they're not always backed up by what you might call scientific proof or objective reasoning.
He's the Family Guy of sports journalism (hence the Sports Guy). Sometimes he's outrageous and borderline ridiculous or even offensive, and other times you can't understand anything that he's writing about because of all the obscure references, but you just have to remember not to take him too seriously and enjoy it.
