The Giants addressed their biggest need on defense as NFL free agency kicked off Monday, agreeing to terms with cornerback Paulson Adebo, The Post confirmed.

Adebo gets a three-year contract worth $54 million, including $36 million guaranteed, according to NFL Network.

Finding someone to start alongside disappointing 2023 first-round pick Deonte Banks was at the top of the Giants’ defensive needs list. 

Adebo, 25, spent his first four NFL seasons with the Saints. 

He started 51 of the 52 games he appeared in and has 10 career interceptions. 

Adebo’s 2024 season was cut short after seven games when he broke his femur in a loss to the Broncos.

He was a 2021 third-round draft pick out of Stanford, where he was a teammate of Giants inside linebacker Bobby Okereke.

They were quite pleased with the play of rookie Dru Phillips, their third-round pick, as Phillips secured a role as the slot corner. 

Banks endured a rough second season, in terms of performance and, at times, effort, and his lack of development was one reason why head coach Brian Daboll fired cornerbacks coach and defensive passing game coordinator Jerome Henderson.

Adebo graded out as the 97th cornerback in the league last season, according to Pro Football Focus. 

He figures to immediately move into the starting lineup alongside Banks and Phillips.
