"William Clay Ford Sr., overseer of the Detroit Lions, somehow managed to land in the financial red zone. The Lions were the only one of the 32 NFL franchises to lose money during the 2010 season.

Forbes has handed Ford Sr. the honor of being the worst owner in America's most popular sport. The Lions franchise value has gone down 3 percent during the past five years -- despite a beautiful new home stadium -- and the Lions have won just 23 percent of their games with that 0-16 season thrown in for good measure."
