GLENDALE, Ariz. — By the time the first quarter of the Arizona Cardinals’ 41-10 rout of the Los Angeles Rams was over, rookie wide receiver Marvin Harrison Jr. had put his name in the record books, avenging his dismal performance in his NFL debut last week.

Harrison finished the first 15 minutes with four catches on five attempts for 130 yards and two touchdowns, the first two of his professional career. He didn’t catch another ball the rest of the game, but when asked after the game if his first quarter was as good as it gets for a receiver, the 22-year-old grinned.

“Yes,” he said.

Harrison added that he was sure there were areas that needed improvement, but added that he needed to “get the rest of the game working as well.”

Harrison had a streak early in the first quarter where he made three consecutive plays for the Cardinals on three drives: his first career touchdown on a 23-yard pass from quarterback Kyler Murray in the back of the end zone, a 60-yard touchdown pass from Murray on the only play of that drive and a 15-yard pass from Murray early in the next series. Six plays after that final catch, he caught a 39-yard pass on third-and-5.

Murray’s favorite pass to Harrison was her first pass, which was Harrison’s first career touchdown.

“This is great for him. Great for him,” Murray said. “I mean, obviously his first touchdown. To come back here after last week, to get rid of the nerves from last week and put everything aside, just come here and play hard, play together and get a win. It was good.”

Murray went to Harrison on the Cardinals’ first offensive play, but the pass was intercepted by Rams cornerback Tre’Davious White. This came a week after Harrison had just one catch on three attempts for 4 yards.

The plan wasn’t to give Harrison the ball right from the start, coach Jonathan Gannon said. The ball, he added, went “where it was supposed to go.” But Murray said he wanted to get his receivers involved quickly and hoped to motivate them.

“You want to give your guys the ball early so they feel like they’re in the game, get them going and get their energy going,” Murray said. “I think we did a good job of that today.”

Harrison was not particularly impressed by last weekend’s performance, Gannon said.

“He’s a mature, serious person who doesn’t listen to noise and sets high standards for himself,” Gannon said. “He’s trained hard this week and played well.”

“Well, I’m happy for him. It’s nice to see him smile. But yes, he shone.”

A few days after saying his debut was “not that great,” Harrison described his performance on Sunday as “solid.” Harrison was hard on himself, however, because he was responsible for all four of Murray’s incomplete passes against Los Angeles, a stat that caught his eye while watching the scoresheet on the sidelines Sunday afternoon.

“I’m not very happy about it,” Harrison said. “It’s definitely something we need to get under control, but we’ll continue to work on our chemistry as the season progresses.”

He became the fourth rookie since 2000 to record 100 receiving yards and two touchdowns in the first quarter of a game, according to ESPN Research, joining Marquise Brown in 2019, Allen Hurns in 2014 and Torrey Smith in 2011. Harrison’s 130 yards in the first quarter were the most in a first quarter by a Cardinals player in the last 30 years, according to ESPN Research.

Harrison reached 100 yards and two touchdowns in a quarter faster than his father, Hall of Fame receiver Marvin Harrison Sr. Harrison Sr. did this only once in his illustrious career, in the third quarter of Week 9 in 2001 against the Miami Dolphins.

Harrison Jr.’s 130 yards in the first quarter were more than his father had in any game during his rookie season in 1996. Harrison Sr.’s season-high that year was 106 yards in Week 15.

And Harrison Jr. is the first Cardinals receiver with three catches of 20 or more air yards in a game since Michael Floyd did it in Week 17 of the 2014 season. In total, Murray threw five completions that went for at least 20 yards, the most such catches in his career.

The Cardinals’ offense set a new record for scoring the most points in a home game of the Super Bowl era with their 1985 home opener, a 41-27 victory over the Bengals.

Murray was nearly perfect on Sunday, completing 17 of 21 passes for 266 yards and three touchdowns, as well as five runs for 59 yards.

“He was outstanding,” Gannon said. “He’s a top player for a reason. You can put him against anyone. That’s my opinion. And that’s exactly what he did today.”

He was the second player in NFL history with at least 250 passing yards, at least 50 rushing yards and a perfect passer rating of 158.3. Ken Anderson achieved this on November 3, 1974.

On Sunday, Murray scored at least 250 points and ran for at least 50 points for the first time since 2021 (a 24-game streak).

Murray’s 148 passing yards on Sunday were his best in a first quarter. He had never rushed for more than 100 yards in a game to date. Murray is also the seventh quarterback in NFL history to record a perfect passer rating in a team’s home game. He is the second Cardinals quarterback to do so, after Kurt Warner in 2008.

Murray became the first Cardinals quarterback since 2000 to have an 80% completion percentage and three passing touchdowns in the first half of a game, and the third quarterback in the last three seasons to do so in the first half of a divisional game, joining Patrick Mahomes last season against the Chargers and Josh Allen last season against the Dolphins.

“When he’s on form,” Gannon said of Murray, “he’s going to be tough to beat.”

Running back James Conner contributed 122 yards and a touchdown on 21 carries, extending his streak of one-point games to seven, the longest streak in Cardinals history.

“He’s hard to bring down once he gets going,” Gannon said. “But when the running game gets going, you guys know that’s how we want to play. When it’s even and you’re in front of the chains, we’re good to go.”

Arizona dominated time of possession from 36:54 to 23:06, thanks in part to sacks. Outside linebacker Dennis Gardeck tied a career high with three. He believes the last time he had three sacks in a game was during his final college season.

“I honestly like that better than the way we played,” Murray said of the defense. “They just had our backs. They had our backs again. It was a win for the whole team. Complementary football at its best. All three phases of the game were good.”

Sunday’s win was the club’s first at home against the Rams since 2014.
