49ers key matchup No. 2: Anthony Davis vs. Mario Williams

This is the second part in a series that spotlights three 49ers-Bills matchups to watch Sunday, 1:25 p.m. (CBS-TV), at Candlestick Park.Matchup No.3: Aldon Smith vs. Chris Hairston49ers RT Anthony Davis vs. Bills DE Mario WilliamsTale of the tape
Davis (76): 6-foot-5, 323 pounds, third season, Rutgers
Williams (94): 6-foot-6, 292 pounds, seventh season, North Carolina StateAdjust your eyes up a line to take a look at "Tale of the tape."Let's just say that 49ers right tackle Anthony Davis has a different idea of Mario Williams' measurements.When asked about the Buffalo Bills' left defensive end, Davis answered, "He's 6-foot-9, 350 pounds and runs a 4.5 (40-yard dash). He's a beast."Davis exaggerates to make a point. The 49ers do not like to give their offensive tackles much help in pass protection. And Davis knows if he is going to hold up one-on-one against Williams, he might have to play the best game of his NFL career.Williams became the highest-paid defensive player in NFL history when the Bills paid him 50 million guaranteed on a six-year contract that could reach 100 million.Williams was the Houston Texans' surprise No. 1 overall pick of the 2006 draft over running back Reggie Bush. While history showed that the Texans made the wise choice, he never reached the playoffs with Houston before leaving for a big contract.With the fat salary comes huge expectations for Williams in Buffalo. This far, Williams has not produced. Williams has 1 12 sacks in four games."The thing that's happened is he's drawn two and three blockers, so his statistics are what they need to do," Bills coach Chan Gailey said. "When they've singled him, he's created problems. We need to everybody else to pick up the slack."Williams told Buffalo reporters this week that he's been hampered by a wrist injury that has lingered since the end of the exhibition season."I'm a hands-on player, and it's all about power in my game," Williams said. "It's been odd having a little nick and not using it to the full extent."Davis is off to the best start of his career. Last week, New York Jets coach Rex Ryan said Davis is already a premier right tackle in the NFL. On Sunday, he'll face his biggest challenge thus far.

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.
