Pittsburgh Steelers Concept Helmet, Version 2

My current favorite throwback uniforms in football are that of the Pittsburgh Steelers. I really like the Bears and Packers retros, too, but the Steelers are the best. I especially dig the yellow helmets, although I think this white concept design would work well, too.

What is the biggest stylistic oversight in the NFL? It's the ommission of steel grey from the Steelers uniforms, particularly on their helmet. Here we have a steel grey shell with a partial (but larger) steel manufacturing starburst insignia. Yes, of course the logo is solely on the right side.
