Early years

Claiborne was born in Shreveport, Louisiana. He attended Fair Park High School in Shreveport, where he played for the Fair Park Indians high school football team. He was a three-star recruit according to Rivals.com. He played quarterback, wide receiver and defensive back. As a senior he had over 2,000 all purpose yards and 30 touchdowns as a quarterback.

Claiborne was also on the school's track & field team, where he competed as a sprinter. He won the 100 meters at the 2009 Louisiana Outdoor State Championships, with a career-best time of 10.76 seconds, and also ran the fourth leg on the 4 x 100 meter relay squad, helping them earn a first-place finish at 42.06 seconds. He also placed second in the 200 meters at the 2009 Region 1-4A Championships, with a personal-best time of 22.21 seconds.

College career

Claiborne attended Louisiana State University, where he played for coach Les Miles' LSU Tigers football team from 2009 to 2011. After spending his freshman season as a backup in 2009, he started 12 games in 2010 and recorded 37 tackles and a team leading five interceptions as a sophomore in 2010, and was named a second-team All-Southeastern Conference (SEC) selection. Following his 2011 junior season, he won the Jim Thorpe Award, given to the year's best defensive back, earned first-team All-SEC honors, and was recognized as a unanimous first-team All-American.

Professional career

2012 NFL Draft

Claiborne was not perceived as a first-round draft pick prior to his junior season. By midseason, however, he had drawn the attention of NFL scouts and analysts, having erased concerns his sophomore production resulted from playing opposite of Patrick Peterson. Towards the end of his junior season, Claiborne had established himself as the No. 1 cornerback prospect for the 2012 NFL Draft, unanimously projected as a top-6 selection. Claiborne scored a 4 out of 50 on the Wonderlic Test, which is an aptitude test given to NFL prospects to test basic intelligence. After being drafted, Claiborne admitted he "blew the test off" (the Wonderlic test) after seeing that it had "nothing on the test that came with football".

Coming into the NFL draft, Claiborne was predicted to be drafted by the Tampa Bay Buccaneers at the number 5 pick overall or even the 4th overall pick to the Minnesota Vikings. The first day of the NFL draft was held on April 26, 2012. On the first day of the draft, the Buccaneers traded out of the 5th pick to the 7th pick with the Jacksonville Jaguars. The Jaguars selected Oklahoma State University wide-receiver Justin Blackmon with their newly acquired 5th overall pick. The Cowboys then traded with the St. Louis Rams (who had expressed their desire to trade out of the 6th pick in order to collect more draft picks) for the 6th pick, and selected Claiborne ahead of the Buccaneers. The St. Louis Rams received the Cowboys' 2012 first and second round selections (14th and 45th overall) while the Cowboys received the 2012 first round selection (6th overall). Buccaneers drafted safety Mark Barron with the 7th overall pick.

Dallas Cowboys owner and G.M. Jerry Jones explained after Claiborne was selected that Claiborne was the only player the Dallas Cowboys would trade up for in the 2012 NFL Draft, but considered it a far fetched idea because Claiborne was ranked as a top 5 player in the draft with the Cowboys picking 14th overall. Claiborne was ranked number 2 in the Dallas draft board right after number 1 pick Andrew Luck.

Claiborne selected jersey number 24 and joined a crowded defensive back unit featuring former Pro Bowler Mike Jenkins, Orlando Scandrick and newly signed veteran Brandon Carr.

Claiborne officially signed his contract with the Cowboys on Monday, July 23, 2012, just a few days before the start of training camp. Claiborne signed a fully guaranteed deal worth $16.4 million over four years (the Cowboys included an option for a fifth year if they desire) with a $10.3 million signing bonus. There was no offset language in the contract.

Dallas Cowboys

The Dallas Cowboys entered the 2012 NFL Draft with cornerback as their top draft priority and traded up with the St. Louis Rams moving from the 14th to the 6th position, in exchange for a second round (45th) draft choice, in order to select Claiborne in the first round.

Recovering from a surgically repaired wrist, Claiborne missed minicamp and all of the organized team activities but was still named the starter at right cornerback. There were high expectations for him during his rookie season, as he finished with 55 tackles and 1 interception, while suffering a number of minor injuries and being targeted by opposing teams in order to avoid Brandon Carr on the left side.

In 2013, he bulked up from 185 to 193 pounds and seemed motivated to play in the team's new 4-3 defense. His progress was slowed first by a sprained knee he hurt in preseason that made him miss three weeks of training camp and later by a dislocated left shoulder he suffered in the season opener. Forced to wear a harness to stabilize the shoulder and play through the injury, Claiborne had poor performances and was passed on the depth chart by Orlando Scandrick after the third game. He also faced adversity with the death of his father and from missing 6 games with a hamstring injury.

In 2014, he missed most of the preseason with knee tendinitis and an AC joint separation. He began the season as the starter at right cornerback with Scandrick suspended for the first two contests but returned to a reserve role after the third game, even though he made the interception that clinched the win. When told of his demotion from the coaches on September 23, he walked out of the Cowboys' practice facility but returned later that night. On September 28, he sustained a noncontact torn left patellar tendon against the New Orleans Saints and was placed on the injured reserve list after four games. In December, he also had his right knee scoped to strengthen the other patellar tendon. The Cowboys opted not to pick up the fifth-year option of his rookie contract.

In 2015, his rehab from a potentially career-threatening injury went better than expected, regaining his previous form and being able to avoid missing time in training camp. Coming from two previous disappointing seasons, where he only started a total of 10 games, the season ending injury to Orlando Scandrick opened the door for him to be named the starting right cornerback. He ended up starting 11 games, missing 5 contests with hamstring and ankle injuries, while registering 5 passes defensed and no interceptions.

On March 11, 2016, the Cowboys re-signed him to a one-year contract worth $3 million dollars, that could reach a maximum of $3.75 million with incentives.
