3. C/OG Aaron Brewer
It doesn't feel like the lock it once may been that the Lions will re-sign left guard Jonah Jackson. Graham Glasgow has raised his value after an excellent season back in Detroit, and he may find the kind of money he's clear about seeking elsewhere. So there could be an issue, in terms of needing either a starter at left guard or someone with the versatility Glasgow (and Evan Brown before him) has.
Brewer went from undrafted by the Titans in 2020 to a 17-game starter who played every offensive snaps in each of the last two seasons. And he did it at two different positions, left guard in 2022 and center this season. He was Pro Football Focus' No. 11 center by overall grade this year.
Brewer is still on the small side (295 pounds), and he's more athletic and quick than brutely strong. He would be a good fit for the Lions' run schemes though, which are aided by offensive lineman who can move and pull like he can.
Brewer is of course not someone Williams coached directly on the Titans' defensive line. But he is someone Williams' pupils went against in practice for four years, and in that light Williams got to witness Brewer's development into a reliable starter.
If the Lions have a need for a veteran interior offensive lineman, Brewer could be on the list of pivot options in free agency.
