"We're just going to keep working and keep working," he said, "and hopefully we'll be sitting out a lot of fourth quarters."
With their first three-game winning streak since November 2009, the Vikings are rolling, but ever cautious about getting too comfortable.
"If you get too excited over a 4-1 start, you'll drop one and you can't get that back," Rudolph said.
After finishing 9-7 in Munchak's first season and missing the playoffs by a tiebreaker, the Titans have regressed in year two. They entered the game with a league-most 151 points allowed, and for all the good their two turnovers did their tackling was befitting of a team that was second-to-last in the NFL in yardage allowed through the first quarter of the season.
Antoine Winfield picked off an underthrow by Hasselbeck early in the second quarter at the Titans 34-yard line, setting up Blair Walsh's first of three field goals.
The turnover came at a price for the Vikings, because rookie safety Harrison Smith was ejected after a tussle between the two teams at the end of the play. One of the officials tugged Smith away from the pile, and Smith responded by shoving him, drawing an automatic 15-yard penalty and the dreaded disqualification.
The Vikings put enough pressure on Hasselbeck the rest of the game that the absence of one of their best players in the secondary hardly mattered. When he did get the ball out, it often sailed high or wide past his receiver.
"If you swarm to the ball and everybody's having fun playing together, you really can't go wrong," linebacker Chad Greenway said.
NFL Commissioner Roger Goodell attended the game, mingling with tailgating fans before. ... Danielle Kalil, the sister of Vikings rookie LT Matt Kalil, sang the national anthem. ... Peterson rolled his left ankle on the second play of the game, blaming that for distracting his focus. "I came out and did all right in the second half, but I've just got to do better," he said. ... Vikings WR Jerome Simpson was bothered by soreness near his left ankle that kept him from pushing off. ... Titans RB Javon Ringer hurt his left knee and left on a cart in the fourth quarter.
