ST. LOUIS — The Green Bay Packers were on their way to the team hotel the day before the game when the cheesehead factor popped up again.
Coach Mike McCarthy joked it felt like walking down a street close to Lambeau Field. During warm-ups Sunday, fans began roaring, ‘‘Go, Pack, Go!’’ And Green Bay’s traveling wall of sound never let up during a 30-20 victory over St. Louis that was the Rams’ first home loss of the year.
‘‘This is one of the shorter trips for some of our fans, which is still a jaunt,’’ said Aaron Rodgers, who passed for three touchdowns in another record-setting performance. ‘‘I think it’s probably eight hours if you’re busting the speed limit a little bit.
‘‘The chants are incredible and the boos that we had on one of those calls from our fans was incredible. It was louder than the cheers for the Rams.’’
Rodgers threw for 342 yards in Green Bay’s second consecutive turnover-free game, and the Packers’ depleted defense clamped down on Sam Bradford and the Rams (3-4).
Bradford was 21 for 34 for 255 yards and an interception, and was sacked three times.
Rodgers was sacked three times in the first half, but got the ball out a lot quicker the rest of the way.
Rodgers has 150 career TD passes and 42 interceptions, breaking Dan Marino’s NFL record for fewest interceptions at that milestone. Marino had 69 interceptions when he threw his 150th TD pass.
Randall Cobb caught two touchdown passes and Jordy Nelson had eight receptions for a season-best 122 yards and a TD for the Packers (4-3).
Rodgers was 30 for 37, setting a single-game franchise completion record of 81.1 percent with a minimum of 35 attempts. He has guided the Packers to touchdowns on 12 of 14 trips inside the 20 over the last four games.
Steven Jackson ran for his first touchdown of the year, and just the Rams’ 10th overall, to trim the deficit to a touchdown midway through the fourth quarter. But Rodgers made a terrific throw to Cobb for a 39-yard pass that put the Packers up by two scores with 3:06 remaining.Bradford was 21 for 34 for 255 yards and an interception, and was sacked three times behind a patchwork line with just two starters left from the opener. Bradford threw a 3-yard touchdown pass to Austin Pettis with three seconds to go.
