A New Scheme versus the Spread Offense
The Cardinals averaged 3.53 WRs per play and just 0.40 TEs per play in week 1. I have never seen offense personnel figures as extreme and there was mention on the broadcast the Cards had more 10 personnel packages (1 RB, no TE) than all other 31 teams combined in week 1.
As a response, Martindale split the defensive packages between nickel (28 snaps), and dime (25) with 1 spike.
The nickel snaps were each of the standard variety (3 cornerbacks, 2 safeties) with Carr at SCB and none of the big nickel (3 safeties, 2 cornerbacks) used against the Dolphins.
