On a late December day in 1967, after the best season of his young career earned him the Cy Young award and a $30,000 raise, Boston Red Sox pitcher Jim Lonborg went skiing at Lake Tahoe. On his last run, Lonborg formed a ‘V’ with his skis to slow himself down. Rather than braking, he tumbled down the mountain. The crash resulted in torn ligaments in his left knee, a very unhappy baseball team and a new kind of sports contract provision that resonates today.
