If you think about it, the NFL is a lot like Game of Thrones: behemoths who can't say a word besides their own name, scumbags who harm women and children with few legal repercussions, and of course, a whole lot of incest.
Okay, that last one isn't true, but the intense regional loyalty and jingoistic war-like mentality present in every NFL locker room/fanbase is a natural analog to the insanely popular HBO show, where different clans compete for a position of power on the Iron Throne. Which you could call the Lombardi Trophy of Westeros... but I won't, because its too obvious.
The designers over at Stargazer Media decided to lend their house's considerable talent to creating beautiful, minimalist sigils that represent every team in the NFL -- that's 32 total (yes, they even counted the Jaguars as an NFL team). Below are said sigils, separated by division, because I am a dork and can do that off the top of my head.
