Who was the marketing genuis who decided to put Keith Olbermann on the Sunday Night Football halftime show? I used to enjoy Olbermann years ago, when he was a sports guy on ESPN. He and Dan Patrick made SportsCenter fun to watch. Since then, of course, Olbermann has morphed into something different from a joke-cracking sportscaster. Football on Sunday should be an escape from politics, not a reminder of them. So what did I do during the Bears-Packers game when I learned that he would be with us for another season during halftime? Click. Good night.
