Coleman's familiarity with Panthers defensive coordinator Sean McDermott from their time together in Philly and his versatility to play both safety spots make it a solid landing for Carolina.
The addition of Coleman could come in handy if 32-year-old veteran Roman Harper's play declines. Coleman landed at No. 26 on Pro Football Focus' ranking system in 2014 despite playing just 396 snaps.
Coleman's signing won't move the needle, but it's the type of low-level addition that can mean more on the field in November than it does on paper in March.
