Lori, I also wouldn't expect him to, for the same reasons you mentioned. He could maybe confirm or deny whether ESPN has ever dictated any topics as being off limits in a story, or given guidelines as to which topics should be treated with sensitivity. As a fan and a reader, it would be very interesting to hear about what kind of filter might be in place over there.
I wouldn't blame him, or lose any respect for him if he chose not answer though. I've been asked by my boss to do things that I didn't necessarily agree with, and have a lot of empathy for any writer who might be asked to compromise a story for the sake of business. The Daily Show has Brian Williams as a guest last week, and before his segment they made a big deal out of the way news organizations had bent over backwards to land an interview with Mark Sanford. I think it's important that people realize just how dependent the "news" can be on advertising dollars, and how easily it can be compromised in search of those advertising dollars. I'm not saying that that is necessarily happening here, as it seems more likely that ESPN doesn't want to provide negative coverage of a source they consider friendly. I think a lot of people noticed similar prejudices in covering the Brett Favre saga a few months back, and it would be a shame if this becomes a larger trend.
