What exactly were you going to call him out about and what does Jon being the editor of HN have anything to do with it? He just made a comparison of the Harrison Barnes' hype to Jon's hype of the Hawks. I don't see any problem with that or think it was unfair. I'm not sure if he carries a bias against the Hawks either. Most articles I've read reagrding the Hawks seemed pretty favorable.
I think that the point of the article/op was on track about the media in general, I fully agree with that about media expectations. If you are not "reporting", then show me the colors and let me do my own painting. As such, I also tend to think that this team had immense talent and got outplayed/outcoached at several junctures (injuries to key positions and key coaches aside). Hindsight is 20/20, given all facts; On outset, It's okay for a picture to be painted, half full or half empty, while 7-5 is clearly not 12-0, just let me see what was the driving factors behind a reference or quote.
As for Pratt, I usually like his writing ...generally. He seems to cover local schools and sports well enough. However, like a quote taken out of context, when using a reference, from a pseudo-colleague at that (member of the sports media), it should be pointed out or footnoted that persons occupation/location. Is he also a reporter, or a pundit, or a coach, or webmaster, a fan, a blogger, an editor, etc? Most articles will cite that information so one can research, if so inclined, the referenced character to look into further why someone might have made such a statement or taken a position. (again, give me the colors used).
By calling out, I mean to bring to his personal attention via email. But in reality, like yours, my opinion is just that, an opinion.
