Boar Hog"" Jackson, once a college football star, now plays spectacular brands of professional football and baseball, and has quickly become an athletic and cultural icon. Knappascribes that success to a combination of stellar physical skills, ambition, and a restless need to find immediate outlets for his energies. Jackson's ability to make intelligent career decisions and the pleasure he finds working with young people are also highlighted. The focus is on Jackson's image and accomplishments (through the 1989 football seasons), but some hints of his real interests and personality are glimpsed behind the hype.
