The Packers have no fear about going on the road in the postseason. A similar crew to this year’s group won three away games two years ago, then beat Pittsburgh in the Super Bowl.

And the NFC North champion Packers who the West-winning 49ers face Saturday night have gotten healthier as the playoffs approached. They have a decent running game to go with that deep receiving corps Aaron Rodgers throws to.

But Green Bay has two significant questions:

— Can the spotty offensive line neutralize one of the NFL’s most dangerous pass rushes, something it couldn’t do in the season opener?

— Can a defense that has been gorged on the ground at times slow down the league’s fourth-best rushing attack, led by Frank Gore

The Niners also have some uncertainties, notably how second-year QB Colin Kaepernick will handle the playoff pressure for the first time. They do have a secondary that matches up well with Green Bay’s receivers.

The Pack has been through this before and succeeded. Why not again?
