26. Tiki Barber:
Barber was a Pro Bowl running back who played all 10 of his years in the NFL for the New York Giants. He ended his career with an impressive 10,449 rushing yards and 55 touchdowns. Barber also added an additional 586 receptions for 5,183 more yards and 12 touchdowns. Barber was at the top of his game during the 2005 and 2006 seasons, rushing for 1,860 and 1,622 rushing yards, respectively. Despite those lofty totals, he decided to retire after the 2006 season.
Barber was met with a large amount of criticism for his decision to step down. He claimed he wanted to pursue a career in broadcasting. Barber also said he ‘couldn’t take it anymore’ when discussing the incredible physical grind of the NFL. His play was so elite for a running back his age that the Giants reportedly offered him an exorbitant two-year, $50 million contract. That’s a sum most elite running backs of even today would clamor to sign for. Barber turned it down and retired regardless. The Giants still won the Super Bowl the following season. Barber later attempted a comeback in 2011, but no team was interested in signing him.
