It's Lewis' prerogative to talk to whom he chooses. But he also insults his team's customers when he fails to communicate honestly with them -- hiding behind an often-bogus cloak of protecting competitive advantage -- through the local media, the primary source of information for Bengals' fans.
Lot of good stuff in the article. This, however, is a biased view of a reporter. I just don't see a whole lot of inside scoop that coaches can relay to fans through the media, and most of it they do not need to know anyhow. Simply because people want to know sensitive inside information doesn't mean they can or should know such information.
Put yourself in the shoes of all of the Bengals opponents, which is the entire NFL, and think of the information that you think the coach, players and/or front office are not being forthright about, and think whether or not another team having such information about your team gives them an advantage over your favorite team. Because you know they are not missing a word of what the media is reporting. I can think of very few things a coach can tell the "local media" that is not already observable which can be shared with the world without negative repurcussions for the franchise.
