The Green Bay Packers were a mess when they hired Dom Capers as their defensive coordinator two years ago, and the Chicago Bears had issues on offense when they turned to Mike Martz after last season.
Well, now look at them.
The Packers and Bears meet in the NFC championship game on Sunday, and the outcome just might hinge on the chess match between two veteran coordinators.
"Mike has certainly been doing this for a lot of years, and he has a lot of little intricacies that are true to his system, I think, that you never know when that's going to come out," Capers said. "And he knows when he wants to use them and he knows when I think they'll be the most effective against you."
Martz called Capers "a terrific teacher" whose teams have always been "well schooled." And Green Bay's defense sure earned high grades this year, helping the Packers get to the conference championship despite a list of injuries that would have derailed many teams.
The Bears, meanwhile, looked as if they were coming off the tracks before making some key adjustments on offense and turning their season around.
Now, these teams are facing off for the 182nd time and the stakes have never been higher. Only once before have they played in the postseason, and that was a week after the bombing of Pearl Harbor, when Chicago beat Green Bay at Wrigley Field on the way to the championship.
Finally, they meet again in the playoffs.
Franchises with a combined 21 championships and 47 Hall of Famers -- with icons on both sides such as Halas, Butkus and Ditka, and Lombardi, Starr and Nitschke -- are set to go at it for a spot in the Super Bowl.
It's a chance for young and talented quarterbacks Aaron Rodgers and Jay Cutler to cement themselves among the best at their position, with two of the league's stingiest defenses staring at them.
Then, there are the coordinators.
"They show you a lot of looks," Cutler said. "They're really good. Dom Capers does a great job of preparing each and every week and keeping offenses off balance, which they've done to us in the past."
Statistically, it looks like a mismatch.
Capers is leading the fifth-ranked defense, while Martz's offense ranked 30th, but the improvements the Bears made on that side of the ball during the season helped lift them to the NFC North title and a first-round playoff bye.
For Green Bay's defense, the work began two years ago. Capers took over a unit that was vulnerable to the big play and couldn't hold big leads. The transition from the 4-3 to his 3-4 set wasn't an easy one, but the Packers made big strides and kept it up despite a string of injuries.
Three defensive starters are on injured reserve and several other key players missed time, but they still have Charles Woodson and Clay Matthews. Also, Tramon Williams developed into a top cornerback.
