The four road wins already is one more than the team had last season (3-5) and in 1999 (3-5). The Packers went 5-3 on the road in the Super Bowl seasons of 1996 and 1997.
"On the road you have your back against the wall," safety Darren Sharper said. "The only people you have in your corner are your teammates and your coaches."
Putting a winning show on the road isn't easy. Only four teams in Green Bay history have won six or more away games: The 1929 team went 7-0-1, the 1962 and 1966 Lombardi teams were 6-1, and the 1972 team was 6-1. The 1941 team was the last to go undefeated on the road, 5-0.
The Packers never won more than five road games in a season under former coach Mike Holmgren, and even finished 2-6 on the road in 1994 when they made the playoffs.
But championship teams need to win more than twice on the road, said Packers quarterback Brett Favre. "Guys always can't wait to get back home and play at home," Favre said. "But you have to believe you can win on the road, and realize how important it is."
The Packers have struggled at times on the road. "We have yet to play a full four quarters in a road game," Favre said.
After playing three straight games at home to start the season, Green Bay sputtered in the first half against Carolina before the defense came to the rescue. At Tampa Bay, Favre threw an interception that was returned 98 yards for a touchdown in a 14-10 loss to the Buccaneers.
Against Minnesota, the Packers once again struggled at the Metrodome and got crushed 35-13. But Green Bay's defense squelched the Bears at Soldier Field on Nov. 11 in a 20-12 win. In Detroit, the team played well and survived a furious rally to pull put a 29-27 win. And at Jacksonville, Favre threw two touchdowns in the third quarter and ran for a third with less than two minutes left to help the Packers win 28-21.
"I don't what the reason is," Favre said. "I really can't explain it. We travel the same way we always have. Guys just have to believe they can win." The Packers are the only road warriors in the league this season. Two weeks ago, the road team winning percentage was the highest in league annals since the 16-game season was introduced in 1978.
"I think that's the crazy makeup of the season this year," defensive tackle Santana Dotson said. "It's been a strange season. I hope the trend continues (this week)."
Green Bay has won three road games in a row for the first time since 1997, when it beat Tampa Bay, Minnesota and Carolina in consecutive weeks.
The 1972 team was the last to win four road games in a row , beating Cleveland, Detroit, Chicago and the Houston Oilers. The 1966 team won five straight road contests, and won eight in a row over the 1966 and 1967 seasons.
"Winning on the road is tough," Favre said. "It's hard, period, to win in this league. We sputtered early in some of those games, and maybe last year, we don't come to win in Jacksonville. You can't afford to take anything for granted."
