Maybe that's because it was nearly three years ago.
"Let's knock on wood," Cobb said.
In the 17 home games since his last Lambeau interception, Rodgers has thrown 41 touchdowns while completing 68.4 percent of his passes for 4,657 yards. The Packers are 15-2 in those games. One of the two losses was the 2013 wild-card playoff game against the San Francisco 49ers, Rodgers' first home game since he returned from his broken collarbone, and the other was the game against the Chicago Bears earlier that season when Rodgers broke his collarbone in the first quarter.
"We know the statistics and what turnovers does to your chances of winning," Cobb said.
For the first time in that stretch, the Packers have the Seattle Seahawks coming to town. Will the home field turn around Rodgers' numbers in his last three losses to the Seahawks? In those three games, all in Seattle, Rodgers has just two touchdowns and three interceptions.
It's not like Rodgers is an interception machine on the road – after all, he's the NFL's career leader in touchdown-to-interception ratio (3.96, or 226/52) – but it's significantly easier for him to run the offense at home compared to loud stadiums like Seattle's CenturyLink Field, which left guard Josh Sitton said this week is one of the two loudest stadium he has played in (the Superdome in New Orleans is the other).
"We have the Lambeau advantage here and love playing in front of our crowd," Sitton said. "I think it'll benefit us."
The Packers went 9-0 last season at home, including playoffs, and haven't lost a regular-season home game that Rodgers started and finished since the season opener in 2012 against the 49ers. Dating back to that game, Rodgers has 55 touchdowns and just five interceptions at home.
So it's no wonder that Rodgers has expressed the desire several times since last year's NFC Championship Game loss at Seattle that he desperately wants homefield advantage throughout the playoffs.
"You can go back and look at all four of our losses [last season] and if one of those goes a different way, we're hosting the NFC Championship game," Rodgers said. "You never know when it's going to be. Your best has to show up every week. You can't have those lapses from time to time. We lost four games last year on the road, took care of our home field advantage. If you do that, it's a recipe to get a bye and you've just got to find a way in our situation to maybe get one more win and then you can host that game late in January."
