Arizona Cardinals head coach Kliff Kingsbury said "you can't ask for anything more" from Colt McCoy after leading the NFL high-flyers to a 23-13 win over the Seattle Seahawks in Kyler Murray's absence.

McCoy started for the third straight game in Murray's absence, due to an ankle injury, completing 35 of 44 attempts for 328 yards and two touchdowns on Sunday.

The 35-year-old quarterback struggled in last week's 34-10 loss to the Carolina Panthers, completing 11 of 20 throws for 107 yards, with no touchdowns and one interception. He also picked up a pectoral injury but bounced back against the Seahawks.

"He was tremendous," Kingsbury said at the post-game news conference. "Last week was an overall struggle. The game plan, the execution was bad, everyone played poorly. That's hard to put anything on him.

"To be in his role and come in and get two divisional road wins against those teams like he did and play as efficiently as he did, you can't ask for anything more.

"He was tremendous. His leadership all week, the way he carries himself, he was awesome."

He added: "He's been through it. He's seen the ups, seen the downs. He knows he can play in this league and play at a high level."

"It's just my responsibility. That's how I see it," Arizona's backup QB McCoy said.

"I came here to be a part of this team and this group, and when your number's called, that's my role, and I'm proud to have won a couple games on the road."

The win moved the Cardinals to 9-2, sitting top of the NFC West division. Arizona also boast a 6-0 away record this season.

Arizona are the third team in league history to win their first six road games by double figures, joining the 1968 Cowboys and 1936 Bears.

"To not have those guys in November at all play, have the best record in football, be undefeated in the division, says a lot about that coaching staff and those player in the locker room," Kingsbury said.

"They continue to fight, continue to work hard, we've just got to continue getting better."
