NBC continues to play musical chairs on Football Night in America, the network's Sunday night blanket coverage of the NFL including a prime time game. (I'm surprised NBC hasn't added Jay Leno to the broadcast!) The latest change is an interesting one: Super Bowl winning coach Tony Dungy is joining the panel and former running back Jerome Bettis is out. What's interesting is that they are two completely different types.

Bettis, whose nickname is "The Bus," is well-known as the smiling winner from the 2006 Pittsburgh Steelers' Super Bowl team. He's loud, boisterous and a larger-than-life personality. Dungy, on the other hand, was the architect and head man for the 2007 Indianapolis Colts' Super Bowl championship. He is cerebral and thoughtful and the author of a bestselling memoir, Quiet Strength: The Principles, Practices, and Priorities of a Winning Life. You could say that the two men are the anti-thesis of each other, which is likely why NBC has made the switch.

At the rate they're going, the 2008 presidential candidates will have made appearances on every kind of TV program before voting day arrives. No show is too insignificant, it seems. (Seriously, if only we could have seen Obama and McCain do the cha-cha on Dancing with the Stars!)

Therefore, it comes as no big shock that on the eve of the election -- Monday, November 3 -- the presidential candidates are going to appear on ESPN's Monday Night Football.

They will be interviewed -- separately on tape -- by half-time anchor Chris "Boomer" Berman. The anticipated time is 10:15 p.m. (ET), but because of the flow of the game, it could be closer to 10:30.
