The Detroit Lions are focused on improving their defense this offseason, particularly their cornerback position where Amik Robertson will become a free agent. With key players set to hit the open market, the Lions must identify capable replacements to bolster their secondary.
Among possible trade targets, San Francisco 49ers cornerback Renardo Green stands out. According to ESPN analysts Dan Graziano and Ben Solak, Green is reportedly an 80% trade candidate, making him a viable option for Detroit’s defensive needs.
Evaluating Amik Robertson’s Performance and Lions’ Need for Change
Robertson started in 14 games over two seasons but struggled significantly in coverage. In the 2025 season, he earned a low overall grade of 48.6, ranking near the bottom among cornerbacks, and allowed 817 yards with six touchdowns—figures that rank among the worst in the league.
This defensive shortfall highlights the urgency for the Lions to consider alternatives in their CB room to strengthen their secondary.
Reasons San Francisco May Consider Trading Renardo Green
Several factors could prompt the 49ers to move on from Green, including a shift in defensive strategy under new coordinator Raheem Morris. Graziano noted,
“The Niners have a new defensive coordinator in Raheem Morris, and Green might not be a scheme fit. The 2024 second-round pick has just one interception in two NFL seasons, and he seemed to fall out of favor a bit with the coaching staff at times last season.” Dan Graziano, ESPN
Green’s mismatch with the new scheme and apparent tension with coaching staff suggest a mutual benefit if he finds a fresh start elsewhere.
Renardo Green’s Potential for the Lions
At just 25 years old, Green has two years remaining on his rookie contract and showed promise during his rookie season. Despite a dip in his 2025 performance, Pro Football Focus rated him notably better at times compared to Robertson:
- 2024 Overall Grade: 69.2 (40th out of 117 CBs)
- 2024 Coverage Grade: 74.3 (16th among 117 CBs)
- 2025 Overall Grade: 54.1 (92nd out of 114 CBs)
- 2025 Coverage Grade: 53.5 (93rd among 114 CBs)
His early success hints at untapped upside that could benefit the Lions, especially given the 49ers’ internal struggles and coaching changes that may have affected his recent performance.
Why Bringing Green to Detroit Makes Sense
Detroit’s cornerback group also suffered notable injuries in 2025, with players like Terrion Arnold, D.J. Reed, and Ennis Rakestraw Jr. missing time. This situation makes acquiring a player like Green a practical upgrade over Robertson.
The Lions could likely acquire Green with a late-round draft pick without a significant financial gamble, a compelling proposition for general manager Brad Holmes as he navigates this offseason.
Looking Ahead: What This Could Mean for Detroit
The Lions face pressure to reinforce a weak spot on their defense, and adding Renardo Green could be a strategic move toward stabilizing their secondary. If Detroit pursues this trade, it may signal a more aggressive approach to rebuilding their defense and provide a fresh opportunity for Green to revive his career.
