In its infancy, the NFL was known as the APFA (American Professional Football Association). The league began in 1920 with eleven teams, of which only four lasted to the end of the season. By 1922, the NFL was officially started, and today only a handful of those teams still exist: The Arizona Cardinals who began as the Chicago Cardinals, the Chicago Staleys who are now known as the Chicago Bears, and the Green Bay Packers. 

Since then, dozens of teams have started as a fresh franchise, moved cities and gone defunct. Almost as convoluted as the comings and goings of NFL teams are their continuous "modernizing" of logos. While some logos stand the test of time, others are flashy and bold. If you consider yourself an elite NFL fan, then it's time to step up and see how many of these NFL teams you can identify from only a small portion of a logo. You might think it's easy enough, but remember - logos, along with their designs and colors, change often.

It's time to break the huddle and line up. We just hope you don't stumble on the five-yard line. It takes the best in the game to figure out all of these NFL logos. Are you up to the challenge?
