In an ever-shifting NFL, entertainment comes in a wide variety of forms.
Many typically associate the notion of fun with a high-flying passing attack led by a star quarterback on an established contender, such as Tom Brady, Aaron Rodgers or Patrick Mahomes. But there's still plenty of reason to be interested in teams that thrive using different formulas, like the hard-charging Cleveland Browns or the stingy Carolina Panthers. And there's often no better way to pique interest than simply by winning, which the 4-0 Arizona Cardinals have down as the league's lone undefeated team.
