Those are literally one of the worse uniforms sets in the NFL.
"What a disaster. The Cardinals start with a very old-school helmet look — plain white shell, basic logo, gray facemask — and pair it with newfangled elements like those clownish jersey sleeves and the league’s worst pants striping. It’s a painfully bad clash of old-school and new-school, and it all looks even worse when they break out the black alternates. Blow it up and start over."
