Kacsmar is one of Football Outsiders writers and is well-known for his acerbic takes and in particular strong dislike of the Patriots. Turns out he posted a TON of racist things over the years and they came to light. Some of them are shocking in how awful they are. He posted racist things against brown folks, Spanish-speaking people, defended "retard" as a pejorative, and against Native Americans as well. Some real terrible shit in there.
He posted a classic non-apology apology yesterday on his account ("I'm sorry you got offended"-style) but I can't see how Aaron Schatz would want him associated with their brand over at FO.
