I haven't done any concepts in a long time, but thought I'd share this one, which is an AZ Cardinals tweak to simplify (even more) their current set.
After staring at the new set endlessly for about a year, and mostly being OK with the addition of Silver into the color scheme, I still think it is not needed. I get that they wanted to modernize the helmet and still keep the "Gray Facemask Aesthetic" as I like to call it, and bring that color into the uniforms, but I'd like to remove it. We now have TWO teams in the NFL (Chiefs and Cardinals) with a color in their logo that is not in their unis (Black for the Chiefs, Yellow for the Cards), and a color in their uniforms that is not in their logo (Gold for the Chiefs, Silver for the Cards).
I like the idea of presenting a new modernized version of the "classic" St. Louis Cardinals uniforms, but I would have taken it a bit further.
I removed the Silver and added Black back as a trim color on the Cardinal Red jerseys. In addition, I completely removed the Red pants, and changed the striping pattern on the White jerseys and pants to Black-Red-Black from Red-Silver-Red. Also moved the wordmark back to the front of the jersey albeit a smaller (but larger than previously worn). So sue me - I like jersey wordmarks. I also added full-color logos to all three jerseys, and changed the facemask color on the White helmets from Silver to Red.
I also added TV numbers to all three jerseys. I understand the trend is to remove these, but I feel that these particular designs need them. I think the current White jerseys look really blank without them.
The biggest change to the Black uniforms is replacing the Silver numeral trim to White - I feel that the Silver trim gets muddy-looking on the Black unis. White stands out better IMO.
I also removed the 3D shading on the helmet decals.
To me, this creates a more iconic look; one that is easily identifiable as the Cardinals, but still retaining some modern elements.
