Team: New York Giants
Seasons played: 1978 to 1987
Type of business: Car dealerships
After playing for the New York Giants for a decade, offensive lineman Brad Benson retired from the game in 1987, a year after "Big Blue" beat the Denver Broncos in Super Bowl XXI. After a stint as a car salesman in the late 1980s, Benson now owns Hyundai and Mitsubishi dealerships in South Brunswick, N.J. The outspoken owner has become known equally in the metro New York City area for his career in the NFL as for his often-controversial radio commercials. For instance, in one ad Benson talks about purchasing a goal post from the old Giants stadium and made an innuendo about "erecting" the 40-foot structure in front of his dealership.
