Early years

Munnerlyn was born three months premature and at birth weighed three pounds, eight ounces. He grew up in Happy Hills, which was a crime-infested part of Mobile. While living there, he attended the Josephine Allen branch of Boys & Girls Clubs of South Alabama.

When he was growing up, his father was murdered and both of his brothers sold drugs. His oldest brother, Timothy, was convicted in 1996 of murder and was sentenced to life in prison. After the shooting, Munnerlyn's mother converted to Christianity and he eventually did the same. Munnerlyn eventually said of the conversion and his mother's prayers that he would stay out of trouble, "Without her prayers, I don't think I could be here in the NFL right now".

High school career

Munnerlyn attended Murphy High School in Mobile, Alabama, where he starred in both football and track. In football, he was a three-time All-region selection and participated in the Junior All-Star Game. He helped lead Murphy High to a 10-2 record and a 6A Regional runner-up finish his senior year, earning a spot on the Alabama Sports Writers Association All-State team. He graduated from Murphy in 2006.

During high school, Munnerlyn was also a standout track & field sprinter. He competed in the 100-meter dash and long jump at the 2004 Junior Olympics. In 2006, he earned a second-place finish in the long jump event at the AHSAA State T&F Meet, recording a career-best leap of 6.85 meters (22 ft, 4.75 in). He clocked personal-best times of 10.53 seconds in the 100-meter dash and 22.39 seconds in the 200-meter dash as a senior.

College career

After high school, Munnerlyn was recruited by South Carolina, West Virginia and Kansas State. He chose South Carolina on January 13, 2006. As a freshman, Munnerlyn was not redshirted and played in 12 games. He missed one game due to an infection in his forearm. For the season, he recorded 36 tackles with his season high of five coming against Tennessee and Houston. Munnerlyn also recorded two interceptions and five pass deflections.

In 2007, as a sophomore, Munnerlyn split time at cornerback and kick returner and was called a "shut down corner" on Rivals.com. Against Vanderbilt, to whom South Carolina lost 17-6, Munnerlyn returned a punt 46 yards and also forced a fumble. In the same game, South Carolina wide receiver Kenny McKinley fielded a punt and flipped it to Munnerlyn who gained eight yards. Following, the season he was named First-team All-SEC.

Head coach Steve Spurrier benched Munnerlyn for the first series against Ole Miss due to Munnerlyn missing class and team weightlifting sessions. Against Kentucky, Munnerlyn returned a kickoff 84 yards before being tackled on the 16 yard line. On the next play quarterback Stephen Garcia completed a touchdown pass to Kenny McKinley. In the same game, Munnerlyn returned a blocked field goal for an 81 yard touchdown.

He declared for the NFL Draft following the 2008 season.

Carolina Panthers

Munnerlyn was drafted by the Carolina Panthers in the seventh round (216th overall) of the 2009 NFL Draft. He called being drafted by the Panthers, "exciting, because I played college ball at South Carolina, and that's only like an hour away. It was exciting to hear my name get called. I'm ready for it, ready to take my game to the next level." In the 2009 preseason, he was competing with wide receiver Ryne Robinson for the punt returner job. In the Panthers second preseason game against the Miami Dolphins, Munnerlyn returned a punt 58 yards and also fumbled one but recovered it, while Robinson fumbled a punt which the Dolphins recovered.

He eventually won the punt return job as well as the third cornerback job beating out C. J. Wilson and Sherrod Martin for the job by the end of September. On November 30, Munnerlyn suffered a concussion against the New York Jets but said days later that he planned on playing in the next game despite the NFL's changing of the concussion policy. Munnerlyn did not play the following week's game but returned the next week against the New England Patriots. He completed the 2009 season playing in 15 games total as the Panthers finished 3rd in the NFC South with 8 wins and 8 losses.

For his second season, Munnerlyn moved up to starting right cornerback after Richard Marshall was not re-signed.

Minnesota Vikings

March 13, 2014, Munnerlyn signed a three-year, $14.25 million contract with the Minnesota Vikings. Munnerlyn ended his first year with the Minnesota Vikings with 60 combined tackles, one fumble recovery, 2 interceptions and 4 pass deflections. Munnerlyn got his first pick of 2015 when he intercepted Matt Ryan in week 12 during a 20-10 win.

Personal

When asked why his name is Captain, Munnerlyn said, "My momma promised my grandmomma that she could name the last child. I was the boy of the family, and she named me Captain. Her great grandfather was named Captain, so I got named after my great-great grandfather. My sisters and brothers have normal names. I got the odd name. In the beginning it was kind of rough. Kids used to tease me a little, but it fits my personality, because I feel like I'm a leader." Munnerlyn majored in criminal justice while at South Carolina.
