3. Duron Harmon
Harmon is a familar name in Detroit. The Matt Patricia/Bob Quinn regime brought Harmon to the Lions from the Patriots (naturally) via trade in 2020, and upon hitting the open market last offseason he landed with the Atlanta Falcons. His Pro Football Focus grade was not good last season (59.1), which provides a chicken-or-egg scenario given how bad Atlanta’s defense was.
Harmon is a versatile safety, capable in deep coverage and able to practically function as an extra linebacker in run support. He has multiple interceptions in five straight seasons, and 140 total tackles over the last two. About halfway through his one season with the Lions he was the fourth-highest graded safety in the NFL by Pro Football Focus–and it’s not as if that defense was any good.
Harmon has turned 31 since the season ended. But that means it won’t take a long or especially expensive deal to sign him as the next wave of free agency rolls, and his leadership intangibles will surely appeal to Lions’ head coach Dan Campbell.
