If you want to predict the future, the past is a good place to start.
So try this: The 2009 Vikings went 12-4 and made it to overtime of the NFC title game. The 2010 Vikings expected the same players to achieve the same results, bringing back all 22 starters on offense and defense. They won half as many games, Brad Childress was fired and Brett Favre finally retired.
The 2017 Vikings went 13-3 and reached the NFC title game. After falling one game short of the Super Bowl (again), they had a choice: run it back and hope for the same results … or learn from the past and recognize that, to borrow a popular phrase, good is the enemy of great.
It's obvious by now which route General Manager Rick Spielman, head coach Mike Zimmer and the rest of the organization's brain trust went. And they should be commended for it.
Pretty much every move the Vikings have made since then can be viewed through two related lenses:
One, they recognized that while they were good in 2017, there was a strong element of luck associated with their success.
The laundry list includes playing (and defeating) Green Bay twice in games impacted by Aaron Rodgers' injury, only playing seven true road games, catching lightning in a bottle with journeyman quarterback Case Keenum and winning a playoff game they had all but given away when a Saints player forgot how to tackle.
(The 2009 Vikings, by the way, were similarly lucky. In starting 6-0, they had the Greg Lewis miracle home victory over the 49ers and a fortunate home victory over the Ravens, who would have won 34-33 if Steven Hauschka had made a 44-yard kick as time expired.)
