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.

Harbaugh goes Biblical, responds to Jacobs' criticisms of his coaching

Harbaugh goes Biblical, responds to Jacobs' criticisms of his coaching

Former NFL running back Brandon Jacobs spent one season with the San Francisco 49ers in 2012 under head coach Jim Harbaugh.

Jacobs only played in two games and gained seven yards on five carries. The results were nothing like his 5,087 yards and 60 touchdowns over eight years with the Giants. 

Apparently being pushed to the bench as a 31-year-old veteran running back didn't sit well with Jacobs. 

“Going somewhere where they don’t have route conversions into certain coverages was just absurd,” Jacobs said Thursday on the Tiki and Tierney Show. “They’re just running routes in the defense, getting people killed. Size and strength is what they had, and that’s why they won.

"Let’s be real. They had great assistant coaches, but Jim didn’t know what he was doing. Jim had no idea. Jim is throwing slants into Cover-2 safeties, getting people hurt. That guy knew nothing, man."

On Saturday morning, Harbaugh responded to Jacobs with a tweet to him. 

Harbaugh went 44-19-1 in four seasons as the 49ers' head coach. He also added five playoff wins and a trip to the Super Bowl in the 2012-13 season, the one that Jacobs played for him.

Shanahan: Brooks earns place on 49ers' first-team defense

Shanahan: Brooks earns place on 49ers' first-team defense

SANTA CLARA – The eldest non-kicker on the 49ers’ roster is learning a new position this offseason.

But Ahmad Brooks has plenty of experience adapting to new positions during his 12-year NFL career. He has played inside linebacker, outside linebacker in a 3-4 and defensive end in pass-rush situations.

Now, Brooks has moved to the strong side linebacker position -- the “Sam” -- in the 49ers’ new 4-3 scheme under first-year defensive coordinator Robert Saleh.

“He’s getting them (first-team repetitions) because he deserves them,” 49ers coach Kyle Shanahan said this week. “Watching how he played last year and then going into this offseason, you never know when a guy who has been around a bunch, if they’re going to feel that they need the offseason like other people do. And Ahmad’s been here every day and he’s needed it just like everyone has anytime you’re learning a new scheme.

“But anytime you have a veteran like that, you worry that, hey, maybe they won’t think that they do need it. But Ahmad has and he’s been here. He’s worked at everything. He’s in good shape. He’s done what we’ve asked in the weight room with Ray and he’s done everything with the position coaches and coordinator on defense. So, I think he’s learning it and he should because he’s putting the work in.”

Brooks, 33, has entered the past three offseasons with his place on the 49ers seemingly in jeopardy. But the 49ers have not been able to find a younger, better player to replace him. Brooks has tied for the team-lead in sacks in each of the past four seasons with 27 sacks over that span.

Eli Harold, Dekoda Watson and undrafted rookie Jimmie Gilbert were the other players who lined up at the Sam position during the first week of 49ers organized team activities.

Brooks and Aaron Lynch, starters at outside linebacker for the 49ers in the previous systems, have the steepest learning curves in the transition to a new defense. Lynch has moved to the team’s pass-rush defensive end position, known as the “Leo.”

“I think techniques are totally different,” Shanahan said. “How you want to take on blocks, how you want to play the run. Ahmad has been around a little longer than Aaron. So he’s probably had a little bit more crossover, some similar schemes.”
