2. S Duron Harmon
Harmon followed his one season in Detroit (2020) by spending the 2021 season with the Atlanta Falcons. Then he spent last season with the Las Vegas Raiders. He set a career-high with 86 total tackles (and 63 solo) last year, while adding two interceptions (one he returned for a touchdown), five pass breakups and two forced fumbles. He earned a 77.6 coverage grade from Pro Football Focus as well, though a 120.0 passer rating against last year runs contrary to that good grade.
And yet, the talent-dearth Raiders (on the defensive side of the ball, if not everywhere) have had no interest in bringing the veteran safety back. It has to be an age thing right? Harmon is 32 years old, albeit with three Super Bowl rings on his resume from his time with the New England Patriots (2013-2019).
Harmon has not missed a game since his 2013 rookie season with the Patriots. He has played more than 1,000 snaps in each of the last three seasons, across the aforementioned three teams and as he has approached and crossed into his 30s.
A veteran safety who can clearly still play a little, has rarely left the field three years running now and doesn't miss games has to have a place somewhere. Unless he has a physical issue teams are aware of but hasn't been made public, Harmon should be on a team right now. And he'd probably penciled in as one of the starting safeties for many teams.
It doesn't seem like Harmon is ready to retire either, unless he's made that known behind the scenes if he doesn't find the absolutely ideal situation. There are just few viable explanations, beyond his age as a flimsy one, for why Harmon is still available as the start of June nears.
