Wes Kull:

This is not an exercise in nostalgia but an interpretation of the league’s founding principles through the symbols that we, as football fans, identify with most.

Many NFL franchises — Patriots, Broncos, Rams, Lions — have updated their uniforms and logos to a swooshed-out, dropped-shadowed, and more commercial-ready image, ignoring a good deal of their team’s heritage and the original rough-and-tumble character that the league stood for.
