In the book, Nolan recounts his first meeting with Snyder, during which he says the new owner asked him if he would work harder if guaranteed a $50,000 bonus.
Nolan said he would work just as hard with no promise of a bonus. Snyder, according to the book, responded in part by saying, "You're probably another one of those guys who lets his wife tell him what to do."
The most famous incident, however, concerned ice cream.
Early in the season, Snyder told Nolan his defensive calls were "too vanilla." A few days later, according to the book, a gallon of ice cream (Rocky Road? Cherry Garcia?) materialized on Nolan's desk with the note, "This is what I like. Not vanilla."
Nolan laughed and sent a note to Snyder that read, "Thanks for the ice cream. My kids enjoyed it."
But after a 38-20 loss at Dallas in Week 6, Nolan returned to his office late that night to find three giant canisters of melting ice cream and this note: "I wasn't joking. I do not like vanilla."
This time, according to the book, Nolan didn't laugh.
The ice-cream caper was reported at the time in the Washington Post. A Snyder spokesman first denied it happened, then later sought to pin it on Redskins executive Vinny Cerrato, a former member of the 49ers' front office.
The Post also asked Raiders coach Norv Turner -- who in 1999 was the Redskins' coach -- whether it should print an apology to Snyder for reporting falsehoods about the ice cream.
"Absolutely not," Turner told the Post. "Not only did he do it to Mike, he said to me the next year, 'Do I have to send you ice cream, too?'"
