TONIGHT'S MUST-SEE

"Monday Night Football," 2 p.m., ESPN. One of the top shows in TV history has switched networks. For 36 seasons, "MNF" was an ABC staple, often reaching the top 10 in the ratings. In prime time, only "60 Minutes" has gone longer. But ABC said it was losing too much money on it and stepped away. NBC grabbed network rights, which moved to Sundays; ESPN (owned by Disney, which also has ABC) grabbed cable rights and a Monday schedule. Now ESPN will revive an old idea: Put a third person in the booth who is neither a play-by-play guy nor an ex-player. That idea sometimes worked for ABC with Howard Cosell and Dennis Miller. ESPN has Tony Kornheiser, a sportswriter who knows more about football than those two. He'll be with play-by-play guy Mike Tirico and analyst Joe Theismann. Michelle Tafoya and Suzy Kober work the sidelines. The game — Oakland at Minnesota — is minor, but the fun will be in seeing "MNF" return.
