He finished the Scarlet Knight's season opening 63–13 victory over the FCS's Norfolk State with three receptions, 129 receiving yards, and three touchdowns.[9] On September 13, he was suspended indefinitely by Rutgers after he was arrested and charged with simple assault for his role in an altercation that occurred after the team's game against Washington State.[10][11][12] After charges were dropped, he was reinstated on October 7.[13][14] He returned in time for Rutger's game against #4 Michigan State on October 10, 2015, and finished the 31–28 loss with a season-high seven catches for 134 receiving yards and a season-high three touchdowns.

Immediately after finishing his collegiate career at Rutgers, some draft analysts projected Carroo as a second, third, or fourth round selection. He was invited to the NFL Scouting Combine but was not able to complete the entire workout due to an ankle injury. At Rutger's Pro Day, he did not perform any drills or workouts due to the same ankle injury he suffered in October 2015. Although scouts were impressed with his physical traits, NFL size, ball tracking abilities, run blocking, and strong hands many were still worried about his character and speed.[16]
Carroo was selected by the Miami Dolphins in the third round, 86th overall, in the 2016 NFL draft.[18] The Dolphins traded their 2016 sixth round pick (186th overall), their 2017 third round pick, and their 2017 fourth round pick in order get the 86th overall pick to draft Carroo.[19] Carroo was upset after falling to the third round.[20]
On May 24, 2016, the Dolphins signed Carroo to a four-year, $3.10 million contract with a signing bonus of $700,388.[21]
On September 10, 2016, Carroo made his first career start in the Dolphins' season and made two receptions for 14-yards in a 12–10 loss to the Seattle Seahawks. He started in place of DeVante Parker who was unable to play due to a hamstring injury. The following nine games, he was unable to log a reception and only received two targets after Parker returned from injury. On November 27, 2016, Carroo made a game-winning 15-yard touchdown catch after replacing Parker who left the game with an injury. It was his first career touchdown and sealed the Dolphins' 31–24 victory over the San Francisco 49ers.[22]
In 2017, Carroo played in 14 games, recording seven receptions for 69 yards.[23] He was placed on the reserve/non-football injury list on December 28, 2017, after having undisclosed emergency surgery on Christmas.[24]
On September 1, 2018, Carroo was waived by the Dolphins and was signed to the practice squad the next day.[25][26] He was promoted to the active roster on October 24, 2018.[27] On the season, he had two receptions for 94 yards and a touchdown.[28]
After not being tendered as a restricted free agent by the Dolphins after the 2018 season, Carroo was suspended the first four games of the 2019 NFL season in June 2019.[29] He was reinstated from suspension on October 1, 2019, but remained a free agent.
Personal life
At age 13, Carroo's mother sent him to live with the Yankovich family in Ramsey, New Jersey. His parents decided that sending him 70 minutes away from their home in Edison, New Jersey was the best choice and much safer than staying in his hometown. He lived with the Yankovich's until he graduated from Don Bosco Prep in 2012. After graduating, he chose to attend Rutgers University in New Brunswick, New Jersey to be closer to his sister Kenisha who lived in Edison.[20]
