John Belushi's widow, Judy Belushi, hired Tanner Colby to write a John Belushi biography. Along the way, he writes, "I re-reported and rewrote one of Bob Woodward’s books," the 1984 "Wired: The Short Life and Fast Times of John Belushi."

Once you have the facts, you have to present those facts in context and in proportion to other facts in order to accurately reflect reality. It’s here that Woodward fails.

Colby catalogs numerous instances of points in Woodward's book where he says the reporter gets facts right but gets their significance wrong.

"Whenever people ask me about John Belushi and the subject of Wired comes up, I say it’s like someone wrote a biography of Michael Jordan in which all the stats and scores are correct, but you come away with the impression that Michael Jordan wasn’t very good at playing basketball."
