Cardinals
Team vibe
Arizona is 1-1 under Mike LaFleur after its offense was held to 151 total yards by Seattle. The backfield was spread among Jeremiyah Love, Tyler Allgeier and Bam Knight, but the team finished with 70 rushing yards and did not generate enough passing production to compensate.

On screen
Look for: Watch the time between the snap and beginning his throwing motion, along with whether his target already has visible space from the nearest defender.
If you see it: If the ball repeatedly comes out before Arizona’s rush reaches him and receivers catch it in stride, San Francisco is staying ahead of the defense’s reactions.
Here's what it means: is identifying favorable matchups early, allowing the 49ers to move the ball without relying on extended plays or difficult throws.
On screen
Look for: Before the snap, look for or an inside linebacker moving close to the line rather than remaining at normal coverage depth.
If you see it: If those defenders cross the line quickly or force to move before throwing, Arizona is creating pressure through positioning rather than waiting for an outside rusher to win alone.
Here's what it means: The Cardinals are making San Francisco account for pressure from several locations, which can complicate ’s otherwise quick decisions.
On screen
Look for: At the snap, check whether one defender lines up tightly over while a second defender or safety leans toward his route.
If you see it: If two defenders converge on and Arizona’s wide receivers are left with single coverage, San Francisco is challenging to distribute the ball elsewhere.
Here's what it means: The 49ers view limiting as the first step toward forcing Arizona out of its most dependable passing connection.

The Stakes
A San Francisco win would move the 49ers to 3-0, while an Arizona win would leave both teams at 2-1. Beyond the records, this game provides an immediate measurement of whether Arizona’s Week 2 offensive problems persist against a defense that recently generated pressure from several positions.
