"Protection, when you get into that type of game and you're behind, it's going to struggle. We've got to figure out ways to start faster, both sides of the ball," the coach said after calling the start sluggish.
Indeed, as Arizona rushed for 30 yards and a score on 18 carries Thursday and is averaging just 77.7 yards per game on the year.
It's no coincidence that the Cardinals, given their struggles in pass protection and establishing the run, have now lost eight straight games to fellow NFC West teams. One thing Seattle, San Francisco and St. Louis do well is rush the passer.
That makes a veteran like Palmer so valuable to the Cardinals. He knows he and Arians weren't brought in to turn this thing around in one year, even if both say playoffs are still the goal, with Palmer pointing out that Arizona is by no means out of the postseason hunt.
The 11-year vet has also stayed away from calling out individual players or units.
"Everybody needs to step up their game, mainly me being the quarterback. That's your job. But we've got to keep growing. There's not enough things (that) got better, obviously," said Palmer.
The backup quarterback is always the most popular player in town and there are probably more than a few in Arizona who have seen limited success this year by the likes of Nick Foles, Brian Hoyer and Thad Lewis and wonder why that can't be Ryan Lindley or Drew Stanton.
Hoyer, for instance, was one of four quarterbacks to throw a pass for the Cardinals last season and had helped lead the Cleveland Browns to a pair of surprising wins this season in Weeks 3 and 4 before suffering a season-ending injury.
But few both inside and outside of Cleveland saw that coming and Palmer has shown he has the right head on his shoulders to navigate the Cards through this process, even if he isn't the distant-future solution under center.
"This game, if you get frustrated that's when you get beat," noted Palmer. "You've got to continue to fight, you've got to continue to try and get better. As soon as you stop doing that, you need to stop playing."
A few more games like Thursday and not many would blame Palmer if he did just that.
