A few minutes before the second half started in Sunday’s game against the Seahawks, the Cardinals showed a video advising fans how to leave State Farm Stadium in case of emergency.

Amazingly, no one bolted for the exits after living through a disaster of a first half.

The Seahawks led by 17 points at halftime, during which the Cardinals reminded us they weren’t always bad at football by inducting former quarterback Carson Palmer into their Ring of Honor.

The 27-10 loss to the Seahawks left the Cardinals (0-3-1) winless in the first month of the season for the second consecutive year.

Worse, both seasons featured the team playing three of its first four games at State Farm Stadium.

Over the past two seasons, which coincidentally coincide with changing the stadium’s name, the Cardinals are now 1-9-1 at home.

The only way out of this for the Cardinals, coach Kliff Kingsbury told us after the game, is for players to stick together, keep working on technique and fundamentals and understand that “nobody’s coming into the locker room to help us,” he said.

That is true, and also foreboding, because it’s hard to see the Cardinals improving much as currently constructed.

They don’t have enough impact defensive players to flip a game, and tight ends who make the Pro Bowl this season will have at least one thing in common: they played against the Cardinals.

The Cardinals make far too many mistakes on offense, quarterback Kyler Murray looks skittish too often and the whole offense doesn’t find rhythm until it’s nearly closing time.

Anything else?

Oh, yes, leading them is a coach, Kingsbury, who has no prior NFL experience and is beginning to sound a bit like Steve Wilks, minus the lectures on the importance of gap integrity.

“I like the competitive spirit we’re playing with,” he said. “I think execution is lacking at times, and that’s on all of us.”

Not much of this is Kingsbury’s fault, however. His offensive game plans are creative and varied. It’s easy to see the logic behind them and what he’s trying to accomplish.

But he’s saddled with a roster lacking in talent because his boss, General Manager Steve Keim, has made mistake after mistake, especially when it comes to drafting good players.

Cardinals fans prefer Keim to be escorted out by security now, although that serves little purpose. But if there is no significant improvement, cardboard boxes should await Keim when he reports to work on Dec. 30, the date after the season ends.

The Cardinals are headed toward having a top five pick in the 2020 draft, and do they really want the man who took Jonathan Cooper, Haason Reddick and Robert Nkemdiche in the first round running that one, too?

The Cardinals’ record in Keim’s first three years on the job (34-14) warranted him trying to fix the problems that resulted in last year’s 3-13 record. But the Cardinals have won just three of their past 20 games, and with each week, it’s becoming increasingly apparent that Keim’s effort is failing.

Tying Detroit and playing the Ravens competitive on the road were encouraging signs that the Cardinals were on a path to improvement. But the past two weeks, losses at home to Carolina and Seattle, bashed that idea into confetti-sized pieces.

Team President Michael Bidwill is to blame for this, too, since he and his family own the product.

Both Bidwill and Keim were on the field at halftime for Palmer’s induction, and Cardinals fans showed respect for Palmer by not booing the executives responsible for the past two years.
