The NFL Insiders think the 1-3 Arizona Cardinals must find a way to win their next game even with Carson Palmer out with a concussion. (1:29)

The Arizona Cardinals scored big this summer with the airing of the show "All or Nothing," a documentary about the 2015 team that went to the NFC Championship Game.

As the Cardinals prepare to face the 49ers in San Francisco on Thursday night, however, they're on the verge of getting nothing.

They are 1-3. Quarterback Carson Palmer is out with a concussion. The defense has been leaky. The offense hasn't scored a single point in the first quarter this season. They don't look like the 13-3 team from last season.

Considered to be one of the most talented teams in the league, the Cardinals could find themselves falling out of playoff contention early. This wasn't supposed to be on the Cardinals' agenda this year. People in the front office say this is their most talented team. I agree. I have them with 10 blue-chip players, among the best in the league. They traded for Chandler Jones, a pass-rusher who had 12.5 sacks for the Patriots last season. They drafted defensive lineman Robert Nkemdiche, whom they considered a top-five prospect.

What's scary is the Cardinals are dangerously close to having their Super Bowl window close. While general manager Steve Keim, one of the best in the league, has done a great job of finding good young talent, they have age and free-agent concerns coming up after the season. Palmer is 36, and Larry Fitzgerald is 33. Jones, Calais Campbell, Evan Mathis, Michael Floyd and Tony Jefferson will be free agents.

How can Arizona avoid a lost season and turn things around? After talking to people around the league, here are a few improvements they can make to get back to their best.
