Johnson's signing with the Saints came soon after being projected as a potential late-round draft pick.
The player was offered a three-year deal worth $85,000 with $10,000 in signing bonus.
A former grad transfer from Penn State University, he played eight games as a senior in 2019.
His limited appearance was a result of a lower leg injury. However, Johnson returned to the team against the Duck's on-field encounter against Colorado on October 11.
In his final game for the Oregon-based college team, the wide receiver secured the final first down needed to win the Rose Bowl in January 2020.
He led his team in receiving the Rose Bowl with five receptions for sixty-six yards, including the final twenty-eight-yard reception helping his team win with 28-27.
In 2019, the athlete had secured a number of pivotal plays for his team, including two receptions on the final drive against Washington State that saw the Ducks clinch a last-second field goal which Johnson contributed to set up.
During his maiden spell at Oregon, the player secured thirty receptions for four hundred seventy-six yards and four touchdowns.
Johnson capped off his illustrious college career with one-hundred-eleven receptions for fifteen-hundred-ninety yards and six touchdowns.
And in his career, one person who has been by his side through ups and downs is his spouse.
In an Instagram post dated December 17, 2021, Johnson posted a picture with his wife. In the caption, he alluded that his partner had remained by his side in his professional endeavors.
