People get serious about their football allegiances. In fact, most are more passionate about their team's colors than about their political party. On Sundays, it's time to put on the jersey, paint the face and, depending on the team, strap on some crazy head gear and do some tailgating. The NFL Shop is the best place to make sure the right team is represented — they boast the biggest selection of jerseys, tailgating gear, collectibles, hats and decor on the web. From the NFL site, shoppers can sort by team or category and even pick up gear from past NFL legends, including Dan Marino, Barry Sanders, Joe Namath and John Elway.
