Cardinals DC Nick Rallis Buys Time With Schematic Overhaul Vs. Rams

TEMPE, Ariz. — The hot seat cooled for Nick Rallis on Sunday. Whether it stays cool depends on whether the Cardinals’ defensive overhaul against the Rams represents a schematic breakthrough or a one-week matchup anomaly.

Arizona’s defensive coordinator entered Week 6 having surrendered 31 or more points in four consecutive losses. His unit ranked last in the NFL in yards allowed per play (6.4) and 30th in points allowed (29.8). Head coach Mike LaFleur‘s public vote of confidence Monday — “I trust the human, I trust the worker” — carried the weight of a GM backing a quarterback after three interceptions.

Against Los Angeles, the Cardinals held the Rams to 13 points through three quarters. Matthew Stafford finished 18-of-29 for 216 yards with zero touchdowns and a 72.4 passer rating. Puka Nacua, targeted 15 times, caught eight passes for 71 yards — a 8.9-yard average that neutralized the league’s most dangerous YAC receiver.

The schematic shift was visible pre-snap. Rallis deployed six-defensive-back packages on 68% of snaps, per Next Gen Stats, up from a season average of 41%. He disguised Cover-2 shells that rotated into Cover-3 match zones, forcing Stafford into checkdowns. Jordan Burch’s first-quarter pressure on third-and-7 — a simulated blitz that dropped eight into coverage — resulted in an incompletion and set the tone.

“We just had to unlock it somehow, some way,” LaFleur said. “This was just one week, but it was a step in the right direction.”

The step came with caveats. Los Angeles played without Cooper Kupp (ankle) and lost Demarcus Robinson to a concussion in the first half. The Rams’ offensive line, missing Steve Avila and Joe Noteboom, started two backups. Arizona’s pass rush generated pressure on just 29% of dropbacks — below the league average of 34% — but the coverage held long enough for the front to arrive.

Budda Baker’s sack, his 3.5 this season matching a career high, came on a delayed blitz from the slot. “Tell Nick to call me on some pressures, you know?” Baker said afterward. The safety has played 84% of defensive snaps, second among NFL defensive backs, raising workload concerns for a 29-year-old Pro Bowler.

Special teams masked offensive stagnation. Chad Ryland’s six field goals — tying a franchise record — accounted for all 18 Cardinals points. The offense converted 2-of-12 third downs and crossed midfield just twice. Jacoby Brissett averaged 5.8 yards per attempt.

“Saw the same thing you saw, six kicks go right up the middle,” LaFleur said. “I don’t know how to coach a kicker, I never will.”

Ryland, claimed off waivers from New England in August, has made 11 consecutive field goals. His 43-yard game-winner as time expired capped a 13-play, 55-yard drive that gained zero yards on first and second down.

L.J. Collier’s 55-yard fumble return on a botched Rams two-point conversion provided the game’s only defensive touchdown opportunity. The 300-pound lineman was tackled at the Los Angeles 35. LaFleur defended Collier’s decision not to lateral: “If that was a non-two-point conversion, then you’ve seen people do it, but I’ve also seen it go haywire.”

The Cardinals (3-3) host the Chargers in Week 7. Los Angeles ranks fourth in EPA per play. Justin Herbert has thrown nine touchdowns against one interception. Rallis’s schematic answers will face a far stiffer test than a depleted Rams offense.

“Obviously we know this is a results-based business,” LaFleur said. One result bought a week. The next one determines the trajectory.
