4. 49ers LB Mark Nzeocha
SAM linebacker Mark Nzeocha is another player who deserves a roster spot in 2019, but not necessarily the starting job he won in 2018. The 49ers are likely to look for a starting-caliber outside linebacker in either the draft or free agency, but Nzeocha would provide much-needed depth at the position. The veteran was also a core special-teamer for San Francisco last season, and nearly made the Pro Bowl thanks to the ballot-stuffing efforts of his fellow Germans. As an unrestricted free agent (UFA), Nzeocha will be able to negotiate freely with other teams if he hits free agency next month.
