Without a game to play last weekend, 49ers offensive coordinator Jimmy Raye switched on the Packers-Cowboys showdown from the comfort of his living room.

"I've got the biggest screen HDTV I could get," Raye said.

As it turns out, it wasn't the most relaxing way to spend a Sunday. Raye watched — in high resolution — as Green Bay's defense throttled the potent Dallas offense.

"They were borderline dominant in that game," Raye said.

Borderline?

The Packers had five sacks, forced three turnovers and held the No. 3-ranked offense scoreless until the final minute of the game.

Overall, Green Bay allows just 282.3 yards per game, which ranks behind the Giants (274.4), the Steelers (277.4) and Jets (281.6).

The challenge for the 49ers offense will be handling the Packers' creativity. Raye said Wednesday that Green Bay coordinator Dom Capers does a good job of cooking up specific schemes based on opponents. Against the Rams, for example, the Packers used three defensive backs and five linebackers.

Raye said he figures Green Bay will focus on running back Frank Gore and tight end Vernon Davis.

"But we're going to go do what we do best after nine weeks, and see how they adjust to stop what we do," he said. "We'll make the adjustments as the game unfolds."

Of particular concern to the 49ers is Packers cornerback Charles Woodson. Instead of playing man-to-man this season, Woodson is being called upon

Also on the watch list is Aaron Kampman, a two-time Pro Bowl player at defensive end who has made the transition to linebacker in the Packers 3-4 scheme.
