One of the biggest offseason moves in the NFL was a billion-dollar deal that affected every franchise. The league switched to Nike as its uniform supplier after 10 years with Reebok, and the new line made its debut as the regular season got underway.
Generally speaking, with the Seattle Seahawks being the notable exception, most of Nike's changes were under-the-hood stuff: Staying cool, keeping dry, feeling comfortable, etc.
Perhaps the most noticeable wrinkle was the addition of designs around the collar, on the sides and in the back.
But much of Nike's media push has focused on the functionality, and that includes the use of roughly a dozen different fabrics on a single uniform to maximize ventilation, durability and comfort.
"Designed and engineered from the inside out, the new uniform focuses on creating a system where the baselayer, padding, jersey and pant work in concert," Nike notes in its press release.
Of course, advances in technology come with unintended consequences or unfortunate byproducts -- or both, if you happened to be watching the Lions-Rams game Sunday. Check out the multi-fabric concept in jarring reality, courtesy of Detroit left tackle Jeff Backus:
