All-whites & all-black alternates: LOVE!
Helmets w/ larger logo & metal flakes: LOVE!
All-reds: I never particularly liked that combo, and that has not changed. Red top would be better with white pants. Interesting that they added "Arizona" on the home jerseys and deleted the shoulder stripes. The size of the "Arizona" lettering pushes the number down oddly low on the jersey. And the home fans already know they're in Arizona! A smaller "AZ" on one shoulder - or an Arizona flag on the shoulders (since they deleted the stripes) would've probably been better.
I like that the all-whites hearken back to the classic unis from the 70s. And I like that they're simple, clean, and classic, not too fussy.
