Dan Campbell said the Detroit Lions' plan in free agency was to make sure they had enough depth at every position so general manager Brad Holmes did not feel forced into taking a position in this month's NFL draft.
On Thursday, the Lions filled one of their last remaining needs in the secondary, signing former Buffalo Bills safety Dean Marlowe.
Marlowe made four starts and had two interceptions for the Bills last season, when he was a key special contributor who saw spot duty in the secondary.
The 28-year-old should compete for time at safety, where the Lions return part-time starters Tracy Walker and Will Harris from 2020. Walker is expected to play a more significant role, while the second starting job appears up for grabs.
