There are a lot of people who will argue that the belief defenses win championships is archaic. When you see people like Aaron Rodgers, Drew Brees and Tom Brady slinging the ball in Super Bowls, you can understand why people believe a good offense is now more important.
Well defenses may not win you a championship, but a bad one can almost guarantee you won't have the chance to ever play for one. There is certainly no coincidence that many of the best teams in the NFL feature some of the best defenses in the league.
Of course, there are a few cases where teams that have a good defense are struggling and a team like the Packers are winning despite a defense that often looks like a leaky boat.
Before we take a look at this list, it should be noted that a statistic many analysts and networks such as ESPN pay a lot of attention to is yards given up. In fact that's how ESPN often ranks defenses. To me, while it's a state worth talking about, I believe it's more important to look at how many points a team gives up, how many turnovers they force and how often they pressure a quarterback.
