Winter is here for the Denver Broncos.

Broncos coach Vance Joseph, retained for the 2018 season, has begun the process of retooling his staff of assistants. According to the Denver Post, offensive line coach Jeff Davidson is being relieved of his duties.

Davidson was hired last offseason to join Joseph, then a rookie coach, as the replacement for Gary Kubiak holdover Clancy Barone. However, the Broncos' front-five, for the second straight year, was among the worst in the league, particularly along the edges with rookie left tackle Garett Bolles and swinging gate Menelik Watson.

Bolles and Watson combined to allow 16 sacks, with the former chipping in seven holding penalties, tied for most in the NFL. As a whole, Denver's OL surrendered 52 sacks (third-most) and 104 quarterback hits in 2017.
