Among the players currently with the Cardinals on a tryout basis are a pair who share the same last name. Running back Justin Jackson and cornerback Josh Jackson have been in Arizona during the team’s minicamp, as noted by team reporter Darren Urban (Twitter link). 
The former was a seventh-round pick of the Chargers in 2018. His workload remained consistent throughout his time there, never averaging more than six carries per game. Not surprisingly, his rushing totals remained almost identical for his first three seasons, though he had a career-year in 2021.
Playing in 14 games last year, the Northwestern alum totalled 364 rushing yards and two touchdowns, averaging 5.4 yards per carry along the way. He added 187 yards in the passing game, to give him a new mark in scrimmage yards (542 yards). That wasn’t enough to earn him a second contract from Los Angeles, however; the team still has Joshua Kelly as a backup to Austin Ekeler, and drafted Isaiah Spiller in the fourth round this year.
In Arizona, Jackson would join a backfield which lost Chase Edmonds in free agency, but still includes 2021 starter James Conner. The Cardinals have also signed Darrell Williams and added Keaontay Ingram in the draft, so Jackson would again face healthy competition for carries.
As for the other Jackson, who was also a 2018 draftee, a deal with Arizona would lead him to his fourth career team. A second round pick of the Packers, he played in Green Bay for the first three seasons of his NFL tenure, totalling 86 tackles and 12 passes defensed. Last August, he was traded to the Giants for fellow corner Isaac Yiadom.
The Iowa product didn’t see any playing time in New York, however, and was ultimately waived in October. He was quickly signed onto Kanas City’s practice squad, and ended up making two appearances with the Chiefs. Like his namesake, Jackson could find a depth role on the Cardinals’ roster to fill out their CB room.
