Roster Depth chart More camp battles
A year ago, Brock broke training camp as the 49ers' No. 3 cornerback and promptly intercepted passes in his first two games. But then he was sidelined due to hand surgery and never regained his role from then-rookie Chris Culliver. Brock was forced into action in the NFC championship game in the sub package when starter Tarell Brown was injured, and he was in coverage on Mario Manningham's important fourth-quarter touchdown.
Cox is seeking to make a return to the NFL after the Denver Broncos cut him last summer. Cox was acquitted on sexual abuse charges in March and the 49ers almost immediately signed him to a contract. (There is no word from the NFL on whether Cox will face punishment under the league's policy on personal conduct.) Brock might be a better cornerback than Cox, but Cox has versatility on his side. He can play cornerback, nickel back and also return kicks and punts. That could give Cox an edge as the 49ers' fourth cornerback because he could also be active as the backup return man.

Report: 49ers receive permission from Broncos to interview O-line coach

Report: 49ers receive permission from Broncos to interview O-line coach

John Benton, who coached on the same staff during Kyle Shanahan’s four seasons with the Houston Texans, has reportedly received permission from the Denver Broncos to interview with the 49ers.

The Broncos hired Benton on Jan. 15 to work as the team’s assistant offensive line coach under line coach Jeff Davidson.

But Denver coach Vance Joseph and general manager John Elway provided Benton permission to interview with the 49ers, Denver’s 9News reported. The Sacramento Bee was first to report the 49ers were looking at Benton.

The offensive line coach is the last major position that remains vacant on Shanahan’s staff.

Benton worked last season as Jacksonville’s assistant offensive line coach. He worked the previous 13 seasons as offensive line coach with the St. Louis Rams (2003-05), Houston (2006-2013) and Miami (2014-15).

Shanahan’s first NFL coaching job was with Houston in 2006, when he coached wide receivers. Shanahan became the quarterbacks coach with the Texans in 2007 before spending the next two seasons as offensive coordinator under then-coach Gary Kubiak.

The 49ers announced nine additions to the coaching staff on Friday.

Also, the 49ers are expected to hire Daniel Bullocks as assistant defensive backs coach, according to The Sporting News. Bullocks worked in the same role with the Jacksonville Jaguars last season. The Jaguars' linebackers coach last season, Robert Saleh, is the 49ers' new defensive coodinator. Bullocks appeared in 31 games in three NFL seasons with the Detroit Lions in 2006 and '08.
