Murray's Cardinals riding confidence wave after staying unbeaten in Rams win

Kyler Murray said the Arizona Cardinals are riding a wave of confidence after emerging as the NFC's lone unbeaten team following their win against the Los Angeles Rams.

The Cardinals improved to 4-0 for the NFL season thanks to a Murray-inspired 37-20 victory over the Rams in the battle of two undefeated franchises on Sunday.

Arizona quarterback Murray passed for 268 yards and two touchdowns, while running for 39 more yards as the Cardinals dismantled the Rams at Sofi Stadium, ending a run of eight straight defeats against a Sean McVay-coached team.

Murray became just the third player in the Super Bowl era with a 4-0 record, completion percentage of 75 or better and 1,200-plus passing yards in his team's first four games of a season, after Hall of Famer Peyton Manning and Seattle Seahawks star Russell Wilson.

Murray on Rams' locker room unity

"I was pretty confident coming into this game with the game plan we had, the week of practice we put together, probably the best game plan that I think personally that we've had since I've been in the league," Rams star Murray told reporters.

"With that, being confident in all the guys, this team, I was just confident in going out there and letting it ride. The guys did the same and I can't be more proud of them."

Murray added: "Not really too worried about what other people think. I think the guys in the locker room understand what we're doing, what we're capable of and where we can take it."

The Cardinals have not reached the playoffs since losing to the Carolina Panthers in the 2015 NFC Championship Game.

But, Arizona are attracting plenty of attention this season – the Cardinals have scored at least 30 points and had at least 400 yards of offense in every game.

"Not a statement," Cardinals head coach Kliff Kingsbury said. "We wanted to get a week better. Division games are important. We've got to continue to play physical football and clean some stuff up."
