The San Francisco 49ers are not expected to retain defensive line coach Jeff Zgonina, according to Alex Marvez. Zgonina just completed his second season as the 49ers d-line coach, and his fourth as an NFL coach. Previously he spent one season with the New York Giants as an assistant d-line coach, and the same role for a year in Houston.
The 49ers defensive line had its share of ups and downs. DeForest Buckner had a huge breakout season, and Ronald Blair quietly put together a really solid season. Buckner had 12 sacks, while Blair had 5.
