Legendary Boston Bruins coach Don Cherry once learned that Detroit Red Wings coach Scotty Bowman had planted a spy in his dressing room. "A little guy," Don Cherry later recalled. "Everybody out there knows who I mean."
Before a game one day, Cherry hatched a counteroffensive and seeded his pep talk with misinformation. Then, after sending the spy to get some ice, he delivered a second "real" talk for the benefit of the Bruins.
