For the Vikings' Week 12 matchup against the Packers, we spoke once again to Tyler Dunne, Packers beat writer for the Milwaukee Journal Sentinel, for this week's edition of "Behind Enemy Lines." Here are five questions we asked Dunne about the final regular season matchup between Packers-Vikings.

1. Last time we saw the Packers, they were relaxing. Now, they're on fire. What has occurred over the last five games to make them one of the best teams in the NFC?

TD: Aaron Rodgers has been basically unstoppable for Green Bay with 28 touchdowns and three interceptions that really weren't even his fault. His accuracy has been off the charts, and he continues to find the locate and attack the sore spot in any defense. The moment, Chicago's secondary was on the wrong page two weeks ago — some in single-high, some in Cover 2 — he hit Jordy Nelson for a deep touchdown. Two other trends are also in his favor. A.) The offensive line has stayed in tact and shut down some pretty strong pass rushers. The Eagles didn't even hit Rodgers once outside their one sack. And B.) Eddie Lacy has developed into a dangerous receiver. At 240, he's a load to take down in the open field.

2. The running game struggled up until the Packers' first meeting against the Vikings. Has Green Bay been able to sustain its running game success since?

TD: Lacy averaged 6.9 yards per carry last week, but only had 10 attempts. Until teams decide to take away the deep ball and keep two safeties back, Rodgers will go to the air. At some point, they expect defenses to go to Cover 2 looks — what gave them some problems in 2012. And then they'll really be leaning on Lacy to be a workhorse. That Vikings win was really his breakout game. Since then, it seems like he's been running without hesitation and with that tackle-breaking edge. As the weather worsens, everyone around here expects his role to grow to some degree.

3. What has led to the increase in turnovers created by Green Bay's defense? The Packers have forced 12 turnovers over the last five games.

TD: Pressure up front. Specifically, Julius Peppers. They haven't had a real threat other than Clay Matthews since Dom Capers arrived in 2009. Peppers is making one or two plays a win that change that game. Last week, he dropped into coverage — something the Eagles later said they never expected out of that particular look — and picked off Mark Sanchez for a touchdown. On another play, he clouded Sanchez's vision and Tramon Williams picked off the quarterback. He's getting pressure and allowing Capers to get creative with the X's and O's. This time last year, Capers was forced to get very vanilla.

4. How has linebacker Clay Matthews looked at inside linebacker and how has that helped Green Bay's defense?

TD: He's been a substantial upgrade over what they had. It's been a major position of weakness and with the run defense dead last in the NFL over the bye week, the Packers needed to do something. Matthews gives the Packers about 20 more pounds at that position with more relentlessness. He's still lining up outside on third-and-long's and even as a fifth rusher on the line. Dom Capers is trying to keep him on the move to confuse defenses. But inside, he has helped shore up a hurting position. Of course, it also doesn't hurt to play with a three-touchdown lead. It'll get interesting whenever the Packers are in a close game if Matthews continues to stuff the run.

5. What do the Packers need to do to win on Sunday?

TD: Keep Rodgers on the field. The Vikings' best shot at an upset will be playing a game of keepaway with Rodgers — they'll need to shorten the game and put long drives together. So if the Packers simply string together scoring drives as they did the last match-up, they'll be OK. Still, it's a road game against a hungry team. Anything can happen.
