Stefan Fatsis has titled the first chapter of his new book, “I’m No Plimpton.” Such a disclaimer is necessary because the stunt detailed in the book, A Few Seconds of Panic: A 5-Foot-8, 170-Pound, 43-Year-Old Sportswriter Plays in the NFL, was famously attempted 45 years ago by blue-blood literary (Detroit) lion George Plimpton. Believe him, though: He’s no Plimpton. That’s not to say he’s an inferior writer, but the NFL of today is vastly more popular, enjoys more media exposure, and is far more dangerous to the untrained tyro; in deference to this and the vital statistics mentioned in the subtitle, Fatsis chooses to be a placekicker, for the Denver Broncos. Now, Fatsis is no stranger to participatory journalism, having made himself into a high-level Scrabble player for his last volume, Word Freak. It’s hard to say if his gridiron feats are more impressive, but he’s certainly maintained his storytelling chops to the point where, after finishing Panic, just about any writer will have to admit, “I’m no Fatsis.” Fatsis discusses and signs copies of his work at 6 p.m. at Politics and Prose, 5015 Connecticut Ave. NW. Free. (202) 364-1919.
