Remember the scene at the end of "Raiders of the Lost Ark" when the ark is hauled into a bland warehouse, where it would sit forever? Because that was the thought that went through my head when I stepped into the NFL photo archives. Decades worth of NFL history sit on the shelves, in the form of some of the greatest photos ever taken. Images as old as the wing-T formation sit there waiting to be discovered again. So I had the enviable task of sifting through these images. There were great photos of legends like Kenny Washington, Bo Jackson and Harold Carmichael, plus so much more. What really stood out was how much the game has changed through the years. From leather helmets, to actual sleeves on the uniforms, it's all captured here. It was an NFL history lesson brought to life.
