On one hand, the 2018 San Francisco 49ers trusted 24-year-old cornerback Greg Mabin enough last year to appear in 13 games, even starting one of them.
But on the other, the Niners weren’t exactly featuring a top-flight secondary a season ago — Pro Football Focus ranked San Francisco’s defensive backfield dead last in the league.
Mabin was part of that equation, too.
With two full years under his belt, the former undrafted free agent enters 2019 amid some changes within the 49ers secondary. While his appearances last year help bolster his stock somewhat, the fact he bounced back and forth from the team’s practice squad is a pretty good indicator where he stands on the 90-man offseason roster right now.
