GREEN BAY, Wis. -- Aaron Rodgers summed up the Green Bay Packers' playoff performances since their Super Bowl XLV victory succinctly:

"Not good enough," Rodgers said Tuesday on his ESPN Milwaukee radio show.

And no one needed to remind him of the Packers' record in that stretch as they prepare for Sunday's NFC divisional playoff game against the Dallas Cowboys.

"We've [gone] 1-3 since then, and two of [the losses came] at home," Rodgers said.

On Monday, Packers coach Mike McCarthy said last year's 23-20 loss to the San Francisco 49ers in an NFC wild-card game at Lambeau Field was particularly tough.

The Packers also have a road loss at the 49ers in a divisional game in the 2012 playoffs and a home loss to the New York Giants in the same round of the 2011 playoffs after the Packers went 15-1 in the regular season.

Their only playoff victory since Super Bowl XLV came against a Minnesota Vikings team that had to scratch starting quarterback Christian Ponder at the last minute and start Joe Webb in a 2012 wild-card game.

"I think most people think we should've won because their starter was out," Rodgers said on his show. "But yeah, we haven't played good enough."

And Rodgers wasn't pointing any fingers, either.

His production in his last four playoff games don't match up to the four games in the 2010 postseason, including Super Bowl XLV. During that run, he completed 68.2 percent of his passes with nine touchdowns and two interceptions for a passer rating of 109.8. In the four playoff games since, he completed 63.9 percent of his passes with six touchdowns and two interceptions for a passer rating of 91.6.

"I have high expectations every time I take the field and I think most people do of me, and that’s how I want it," Rodgers said. "The bar has been set high and nobody's going to apologize for setting it, and I'm not sorry for the bar being up there. I love an expectation of greatness because that's what I expect of myself every time I take the field, and I know my teammates expect me to play well.

"I go into the game expecting to play and excited about the opportunity to be a guy that my teammates can count on. I know everybody has a role and my role is an important, just like the other 45 guys that are going to be suiting up. We all believe in each other, and we need each other to 'hold the rope,' as we used to say [in college] at Cal, just do your part."
