What a year for Ray Lewis to retire. In his last year as No. 52, the Baltimore Ravens' linebacker is squaring off against the San Francisco 49ers in Super Bowl XLVII.
Just how valuable has Lewis been to the Ravens?
Forbes estimates that Lewis helped boost the value of the Ravens franchise
by as much as $125 million during his 17 years of play by helping to make the brand more appealing.
"The historic brand appeal of the franchise has helped keep the Ravens franchise value among the NFL’s top third," Forbes writes.
