Coach's big decision: Containing Davis

EAST RUTHERFORD, N.J. -- Giants defensive coordinator Perry Fewell said Thursday he likes linebacker Jacquain Williams’ ability to match up with San Francisco 49ers elite tight end Vernon Davis.

But when asked about covering Davis on Friday, Williams responded, “that’s not my role.”

Regardless, the key to a Giants’ victory this Sunday in San Francisco will likely be containing (since you can’t stop) Davis -- and it’s up to Fewell to figure out how to do so.

In last season’s NFC title game, Davis torched the Giants for 112 yards and two touchdowns, but Big Blue was still able to prevail. The 28-year-old is coming off a season-high 106-yard receiving effort against the Buffalo Bills last week.

The Giants have had success covering tight ends in 2012. Only Carolina’s Greg Olsen has gone off -- snagging seven passes for 98 yards in Week 3.

Looking at New York’s roster, putting Williams on Davis seems to make the most sense. Williams covered the 49ers tight end in last season’s regular-season game, but not in the playoffs. Williams certainly has the speed to keep up with Davis.

But maybe Fewell will decide to put one of his other linebackers on Davis with safety help from Antrel Rolle or Stevie Johnson over the top. Maybe he’ll go with Rolle. Maybe he’ll go with a mix of defenders, since the 49ers like to put Davis all over the field in different formations.

It’s going to be intriguing to see just how exactly Fewell schemes against Davis.
