Mike McConnell is a fantastic talk show host -- informed and opinionated without being a blowhard or egomaniac. His departure from WLW is a huge loss for the station, both financially and from a programming standpoint. He should be a great fit at WGN, where he'll have access to a huge metro area and the funding of Randy Michaels and the Tribune Co.
Though, if the rumors are true, McConnell might not be the only huge departure from WLW in the near future. The face of Cincinnati radio is changing rapidly, and not for the better IMO.
