The Arizona Cardinals were far from their best on Thursday night, as they succumbed to the Seattle Seahawks, 28-21. After the game, Cardinals star quarterback Kyler Murray and coach Kliff Kingsbury were in agreement as to the biggest factor that led to Arizona's defeat: penalties.

The Cardinals received no less than 10 penalties throughout the contest, which resulted in 115 yards. According to Kingsbury, this is a simple recipe for disatser:

“You’re not going to win in this league doing that, especially against a quality team against Seattle,” Kingsbury said, via (h/t Michael David Smith of NBC Sports). “That’s unacceptable to have that many and we got to clean that up. Just got to refocused and be better moving forward. The guys, when that occurs, they’re always feeling bad about the situation and so you just try to make sure we get past it and not allow it to happen against and not allow it to affect us moving forward.”

Murray echoed his coach's thoughts, saying how he believes it were their own mistakes that led to their demise against the Seahawks:

“Probably just the little self-inflicted penalties,” Murray said. “Just really shooting ourselves in the foot. It wasn’t a clean game by any means — easier said than done to play those — but that’s just . . . we got to be better.”

It is also worth noting that Kyler Murray suffered what appears to be a minor knock in the first period of the contest. The arm/shoulder injury did not seem to be serious, but it was enough to have some sort of impact in him during the game.

The former first overall pick completed just 29-of-42 passes for 269 yards and a couple of touchdowns. Needless to say, that was not enough to lead the Cardinals to victory.
