I've read PFT almost daily for the past 4 years. He runs a great site that allows you to get a little bit of new information on every team, new rumors (which are just that most the time, and links to articles on every team. That being said, he is very egotistical, stubborn, and holds a lot of personal vendettas (he has one against ESPN, Matt Mosley, and some other people who have called him out before). He also eats a steady diet of crow.
What he did was totally irresponsible journalism. The damage is done because I highly doubt his apology will get as much press as his defiant, arrogant, and condescending first two articles. That being said, he seems half-way sincere in his apology, and we'd be no better than him if we didn't give him another chance.
(P.S. I would have loved to seen A-Rod on Florio's new online radio show and just completely rip him a new one. Aaron is definitely smart enough and edgy enough to have pulled it off.)
