His third quarter interception for a 60-yard touchdown was his first career touchdown.

On September 25, 2016, Cooper earned his first start as a member of the Cardinals and made seven combined tackles and deflected a pass during an 18-34 loss to the Buffalo Bills. In Week 5, he collected three combined tackles, a pass deflection, and intercepted a pass attempt by San Francisco 49ers' quarterback Blaine Gabbert in a 33-21 victory. During a Week 1 matchup against the Atlanta Falcons, Cooper had a career-high nine solo tackle performance as the Cardinals were defeated 19-38. He completed his only season in Arizona with a career-high 69 combined tackles (63 solo), 11 pass deflections, and a career-high four interceptions in 13 starts and 15 games. Cooper led the Cardinals in interceptions in 2016 with four and was an alternate for the 2017 Pro Bowl. The Arizona Cardinals finished with a dismal 7-8-1 record and did not receive a playoff berth, making it the first time in they finished with a losing season during the Bruce Arians head coaching era.

Cooper became a free agent for the first time in his career after the conclusion of the 2016. He drew interest and spoke to the Pittsburgh Steelers, New York Jets, and Chicago Bears. Arizona Cardinals' Head coach Bruce Arians expressed interest into resigning him but stated that, "The price looks like its going pretty high for him, so we'll wait and see."

Cooper returned to training camp in 2015, facing stiff competition from Phillip Gaines, Marcus Peters, Jamell Fleming, Sanders Commings, and Steven Nelson as all were vying for the starting cornerback job. Head coach Andy Reid named Cooper the fourth cornerback on the Chiefs depth chart to begin the regular season, behind Sean Smith, Marcus Peters, and Jamell Fleming.

He was inactive for the Chiefs' 27-20 season-opening victory against the Houston Texans. On September 28, 2015, Cooper earned his first start of the season after Sean Smith was suspended for the first three games of the season for a D.U.I. arrest. He finished the 28-38 loss to the Green Bay Packers with only one tackle. From Week 5 to Week 10, Cooper was a healthy scratch and was deactivated.

He missed the season-opener against the Tennessee Titans due to an ankle injury he suffered during practice. On September 14, 2014, Cooper made his season debut and recorded five combined tackles and defended two passes during a 17-24 loss to the Denver Broncos. The following week, he recorded a season-high six combined tackles in a 34-15 victory over the Miami Dolphins. Cooper lost his starting cornerback job to Jamell Fleming after returning from a Week 6 bye. For the remainder of the season his role was extremely diminished, even after Fleming missed multiple games due to a hamstring injury. He was a healthy scratch for Weeks 16 and 17. He finished with a total of 21 solo tackles and three pass deflections in 13 games and four starts.

Coming out of Rutgers, Cooper was projected by the majority of NFL draft experts and analysts to be selected in the seventh round or be a priority undrafted free agent signing immediately after the conclusion of the draft. He did not receive an invitation to the NFL Combine due to the fact that Cooper was not a highly projected prospect. On March 13, 2013, Cooper participated at Rutgers pro day and opted to perform all of the combine and positional drills for the team representatives and scouts from all 32 NFL teams. His overall performance was seen as a success and showcased his ability. He was ranked the 40th best cornerback prospect in the draft by NFLDraftScout.com.

The San Francisco 49ers selected Cooper in the seventh round (252nd overall) of the 2013 NFL Draft. He was the 29th and final cornerback selected during the draft.

On September 1, 2013, the Kansas City Chiefs claimed him off waivers and added him to their active roster. Upon arrival, head coach Andy Reid named Cooper the Chiefs' fourth cornerback on their depth chart behind veterans Sean Smith, Brandon Flowers, and Dunta Robinson.

He made his professional regular season debut during the Chiefs' season-opening 28-2 victory over the Jacksonville Jaguars and finished with one tackle. On September 29, 2013, Cooper earned his first career start in a 31-7 win over the New York Giants and recorded a tackle and two pass deflections. He started in place of Brandon Flowers, who was unable to play due to a knee injury. The following week, he recovered a fumble in the end zone for a touchdown, made three combined tackles, three pass deflections, and made the first interception of his career, picking off Tennessee Titans' quarterback Ryan Fitzpatrick in a 26-17 victory.
