ST. LOUIS (AP) — Thirty-eight years ago, the last time the Arizona Cardinals were 4-0, their home was St. Louis and they were known affectionately as the Big Red.
Nearly a quarter century since departing for the desert, they're on top of their game again.
The surprising Cardinals don't have one of the best offenses in the NFL, far from it actually. Throw out the big plays on defense and they're pretty much middle of the road there, too. Their games are going down to the wire, the last one ending in overtime and three of them decided by a total of nine points.
Not surprisingly, they're just a 1-point favorite to beat the St. Louis Rams. On Thursday night, the Cardinals will have a shot at being the first team to 5-0, two wins shy of the 7-0 start in 1974 by a team that featured Hall of Famers Dan Dierdorf, Roger Wehrli, Larry Wilson and Jackie Smith.
One of the advantages to all the close calls is there's no danger of overconfidence.
"Obviously, we're excited to be 4-0," coach Ken Whisenhunt said. "We've had four up and down games. We've had a lot of trauma in them, so there's been a lot of emotion extended.
"But just to be where we are, we're certainly pleased about that."
The Cardinals have had a knack for handling late-game pressure since midway through last year, when they rebounded from a 1-6 start and became the first NFL team to win four overtime games in a season. All eight of their wins last season were by a touchdown or less.
They're still in that mode, winning the 500th game in club history last week after forcing overtime on Kevin Kolb's TD pass to Andre Roberts with 22 seconds to go. The Dolphins gained 480 yards but scored just two touchdowns last week as Arizona won its seventh straight overtime game.
As coaches say all the time, it's a bottom line business.
"They are a hell of a team, they're really well-coached," Rams defensive end Chris Long said. "They're 4-0 and rightfully so, they've done things to win those games.
"It's going to be a great challenge for us. I really mean that."
There's good reason for those words of respect.
The series has been quite lopsided between the club that departed St. Louis in 1988 after big money squabbling thwarted plans for a new stadium, and the franchise that replaced them in 1995 after receiving a bounty of concessions. Among them is a lease that could allow to team to leave after the 2014 season if their domed stadium isn't deemed to be in "first tier status."
The Cardinals have won 10 of the last 11 since the second meeting in 2006, half of them by double digits, and have a franchise-best seven-game winning streak in St. Louis. Punt returns for touchdown by Patrick Peterson fueled both victories last season, one of them in overtime.
