Hockey is the lens through which we see our lives—how we measure right and wrong, how we understand our hopes and fears. So it was for Dave Bidini in 1974, the last year Dave Keon played in Toronto. In a new grade in a new school, Bidini found himself the victim of a bully—a depredation he could understand only by thinking about what the Leafs dauntless captain went through game after game.

Throughout his twenty-two-year career, Keon was only in one hockey fight, in his last game as a Leaf on April 22, 1974. It was on this day that the eleven-year-old Bidini decided to fight back, an occasion that the writer looks back on with breathtaking courage and honesty. But while Bidini would remain a blue-blooded Leafs fan into adulthood, Keon became estranged from the franchise with which he’d won four Stanley Cups, two Lady Byngs, and the first ever Conn Smythe Trophy in 1967.
