From the 1920's into the 1950's, NFL teams wore plain and even indistinguishable wool uniforms with basic color schemes. It really wasn't until the 1950's, as the league's appeal to sports fans began to take shape, that teams began to truly develop an identity. The arrival of the AFL further helped NFL teams develop uniform identities, with teams like the San Diego Chargers wearing bright powder-blue jerseys.http://www.buychinajerseysaz.com
