TEMPE, Ariz. — Coach Bruce Arians sure isn’t going to complain about the Arizona Cardinals’ 6-1 record. He knows his team does a lot of good things: commits few turnovers, doesn’t miss many tackles and doesn’t get rattled when it falls behind.

However, the Cardinals have yet to play a good-looking game, and Arians was unhappy with the number of mental mistakes his players made in a 24-20 victory over the Philadelphia Eagles on Sunday.

“Survivors,” Arians replied when asked about his team’s identity. “We find a way to win. It’s not always pretty. It was another game that going back and watching the tape, we had some really good outstanding individual performances, but as a collective offense, defense, and I’ll throw special teams out there also, we had too many malfunctions.

“The attention to detail has to be better or else it’ll come back and get us.”

The malfunctions included blown blocking assignments and poor, or improper, pass routes. With a difficult schedule ahead, the Cardinals won’t continue to win with that amount of mistakes, the coach believes.

“The mental errors,” Arians said. “The way we talked about running certain routes, the way versus certain coverages, did not show up on film the way we coached it.

“That’s alarming and disheartening in a way, but we still have playmakers. We didn’t block as well as we could have. We didn’t give up any sacks, but they got us off the spot way too many times. The same thing in the running game: It was one guy here, one guy there again, and we thought we had gotten over that.”

Part of problem was a step up in competition. The Cardinals played the Washington Redskins and Oakland Raiders the two weeks previous, teams with one win between them at the time.

The Eagles (5-2) are much better. Their defense gave the Cardinals fits for most of the afternoon, and their offensive gained 521 yards.

Philadelphia also committed three turnovers, including two near the Arizona goal-line. The Cardinals had just one giveaway.

“I would hope that we’d get one of those pretty games, but against the teams we’re playing, it’s going to be survival,” Arians said. “Everybody that we play from here on is in the thick of it. (The St. Louis Rams) might have the worst record, but they’re one of the best teams we’re going to play. Every game is going to be to the wire probably, but it’d be nice to have one that we played as good as we could play.”

–Cornerback Patrick Peterson sustained a concussion against the Eagles and will go through the NFL’s head-injury protocol.

The team has a couple of options if Peterson can’t play. Last week, the Cardinals moved Jerraud Powers from nickel corner to the outside with Tyrann Mathieu taking over the nickel spot. The Cardinals could also put Justin Bethel in for Peterson and leave Powers in the slot.

NOTES: Strong safety Tony Jefferson felt concussion symptoms Monday morning, and he must go through protocol before being cleared to return. … Running back Stepfan Taylor injured a calf in the second half and did not return, so Andre Ellington had all 23 of the Cardinals’ rushing attempts.

REPORT CARD VS. EAGLES

–PASSING OFFENSE: B — QB Carson Palmer completed less than half of his passes (20 of 42), but he threw for 329 yards and two touchdowns. In the three games since he returned from a shoulder injury, Palmer has six touchdown passes and just one interception. WR Larry Fitzgerald’s 80-yard touchdown was the longest of his 11-year career.

–RUSHING OFFENSE — D — The Cardinals gained 71 yards on 23 attempts, a 3.1-yard average. The line created few openings, and RB Andre Ellington was shut down when he tried to bounce outside. Ellington did have a 1-yard touchdown run.

–PASS DEFENSE: B — The Eagles threw for 411 yards and two touchdowns, and QB Nick Foles wasn’t sacked. However, the Cardinals intercepted two passes and stopped three attempts into the end zone in the final seconds. CB Antonio Cromartie made both interceptions.

–RUSH DEFENSE: B — A solid but unspectacular effort. Eagles RB LeSean McCoy gained 83 yards on 21 carries. His longest gain was 13, so he didn’t hurt the Cardinals much.

–SPECIAL TEAMS: B — PK Chandler Catanzaro booted another field goal. He is 16-for-16 this year, the longest streak by a rookie opening his career in NFL history. The rest of the units were solid.

–COACHING: C — Coach Bruce Arians admitted afterward that Eagles defensive coordinator Bill Davis got the better of him. Philadelphia did some things Arizona didn’t expect, though Arians wouldn’t say what. Arians also got away from the run when it was working in the second half.
