We mentioned this the start of the AFC and NFC Championship games on Sunday but the formula for the most successful teams this year has been a great defense plus a great quarterback (even if they don't play like a great quarterback). The Pittsburgh Steelers and Green Bay Packers will meet in the 2011 Super Bowl and they have both of those.
The Steelers are the No. 1 ranked defense in the NFL while the Packers are No. 2. Both know how to attack the passer with outstanding outside linebackers in the 3-4 defense. They'll never be the Steelers but the Chiefs defense is built in a similar manner. They've got a strong pass rusher in LB Tamba Hali and finished the year with the league's 11th ranked defense.
Both the Steelers and Packers also have a top quarterback in Ben Roethlisberger and Aaron Rodgers. Roethlisberger didn't have his best game completing just 10-of-19 passes for 133 yards but he still had a valuable role. Like QB Matt Cassel showed at times last year, you can still be valuable even if you're not putting up 300 yards and three touchdowns.
For the Chiefs, I think the defensive part of this equation is on its way. They may never have the James Harrisons and LaMarr Woodleys sacking the quarterback but the defense is turning into a very good unit. As for Cassel, he's not on Roethlisberger or Rodgers' level yet but he made a huge leap last season. You can see the seeds of this championship formula in the Chiefs.
So what I'm taking out of these Super Bowl teams is a strong defense and an elite quarterback. Anything else that jumps out at you?
