Entering his age-39 season, Campbell is simply a marvel. A magnificent run-stuffer even at his advanced age (he had an 85.9 PFF run defense rating in 2024) and still productive enough as a pass-rusher to be a good third- or fourth-rusher on an above-average defense. With the additions of Josh Sweat, Campbell, and Dalvin Tomlinson, the Cardinals hope they have done enough to bring the floor of the defense up above where it was last season. It’s a good front on paper, even if Arizona’s cornerbacks make us a little weary of forecasting them as a fantasy-worthy defense in 2025. Campbell last played for the Cardinals in 2016, if you’d like to feel a little older today.

Campbell will turn 39 in September and is deciding whether to return for an 18th season. According to Jackson, retirement “isn’t out of the question, either,” for Campbell, who continues to play well despite his age. Campbell totaled 52 tackles and five sacks for the Dolphins last season and has had five or more tackles in each of his last three seasons.

Campbell has mulled retirement for the last several seasons but is now set to join the Dolphins on what is likely a one-year deal. The soon-to-be 38-year-old totaled 6.5 sacks and 10 TFLs in his lone season with the Falcons and is now ready to return to Miami, where he played in college ball from 2005-2007. Campbell should provide immediate help along the interior for a defense that lost defensive tackle Christian Wilkins to the Raiders via free agency and continues to play at a high enough level to be an impact player. Amongst defensive linemen who played at least 300 snaps last season, Calais ranked 39th with a defensive grade of 80.0.

Campbell has mulled retirement over the last few seasons, but was last heard saying he’s “leaning toward playing again.” the soon-to-be 38-year-old lineman totaled 32 tackles, 6.5 sacks, and 10 TFLs in his lone season with the Falcons last year, and could likely be had at a team-friendly price. Morris said he has spoken with Campbell about a return and hopes to re-visit the conversation “at a later date.”
