Arnold had a solid rookie season in 2024, recording 60 tackles (47 solo), 10 passes defended and a fumble recovery. Early on, he had a tendency to commit defensive holding or pass interference penalties but improved as the season went on, and I think that progress that will carry over into his second season.
With opposing quarterbacks knowing Detroit's secondary consists of Kerby Joseph, Brian Branch and D.J. Reed, I have a feeling they'll target the young Arnold, which gives him a shot to make more defensive plays and notch interceptions for a breakout year.
