MAC’S ALL WRITE

Does everyone know that the former bad boy of tennis, John McEnroe, is shopping his autobiography right now? (“F- – – You” would he a good title, but I’m sure they’ll settle on something more sedate.) I understand Mac wants to keep his personal life out of the book, but if he wants a big dollar sale, I think he’ll just have to talk about his strange and troubled former marriage to Hollywood casualty Tatum O’Neal.
