This is what I wrote (summed up my post and added a few things) to OTL:
Speaking as someone who has lived in Chicago all my life, I can confidently say that Jay Mariotti's career hallmark has been to engender as much conflict as possible so that he can milk any kind of story about it. It is well known that he despises Jerry Reinsdorf, hates US Cellular Field and doesn't have a whole lot of love for the players on the team. Last season, he went so far as to say he felt that US Cellular was an unsafe place to take his family and would discourage anyone from going because of two isolated incidents that could have happened (and have happened) at literally every ballpark in America. It's too bad that because he has a relationship with ESPN through one of their shows, he's now ESPN's go-to guy for Chicago. In my mind, he absolutely does not speak for people in Chicago at all.
Do a little research and you'll see that everything I've written above is true. Additionally, last year, he started a war with White Sox television commentator Ken "Hawk" Harrelson and made that the entire focus of his vitriolic rants for at least two months in print and on radio. And speaking of radio, when he was hired and then fired after just several weeks from ESPN 1000 radio for low ratings, he blamed his firing on White Sox upper management and Jerry Reinsdorf (ESPN 1000 broadcasts all Sox games). Yes, Jay, low ratings are definitely a White Sox conspiracy.
Please, please, please reconsider before having him back on your fine show, especially when discussing the White Sox. I find Outside the Lines to be a great show, but put quite frankly, Jay Mariotti is one of the most unfairly biased reporters you will ever encounter in the industry.
