Bill Belichick didn't win a playoff game until his fourth year as an NFL head coach and didn't reach a conference title game until his seventh year.
Don Shula didn't win a playoff game or reach a conference title game until his sixth year as a head coach.
It took Dick Vermeil four years to win a playoff game, Dan Reeves six years, Tom Landry eight.
Heck, Pete Carroll didn't reach a conference title game until his third head coaching stop, and Marv Levy didn't even get to the playoffs until his eighth year as a head coach.
Just a little context.
Pederson has been magnificent this year, and out of everybody we talk about who's played a role in the Eagles' success - from Carson Wentz to Nick Foles, Howie Roseman to Joe Douglas, Fletcher Cox to Malcolm Jenkins, Jim Schwartz to John DiFillippo, Jason Kelce to Alshon Jeffery - Pederson is the common thread that's tied all of it together.
We saw last year that Pederson had a rare ability to keep a team together when faced with adversity. Whether it was the whole Sam Bradford situation before the season, Lane Johnson's suspension, a couple arrests, two players publicly speaking out about mental health, or just keeping the thing on the rails after three straight late-season ugly losses, Pederson won over his players by confronting each issue openly and professionally and treating his players like grown men.

By the time the team training camp ended this past summer, Pederson had earned the respect of the veterans by preaching discipline without being over the top about it and by constantly keeping the lines of communication open with his players.
Here's a young, inexperienced coach who had a long but undistinguished playing career and no real track record or resume as a head coach trying to convince a locker room of Super Bowl winners and all-pros that he knows what he's doing.
But he did that. Just by being himself. Tough, smart, open, honest.
And once you get guys like Malcolm Jenkins, Jason Peters, LeGarrette Blount and Alshon Jeffery to buy in, the younger guys just fall in line.
And that might be the biggest challenge any head coach faces. Getting guys to believe in his message. To believe in him.
But Pederson has tremendous instincts when dealing with people, a real natural, honest way of getting his point across, and it enabled him to seamlessly win over the locker room.
Once that happened, this team was built to withstand whatever challenge it faced. To withstand whatever roadblocks stood in its way.
And as it turned out, there were plenty of them.
We don't have to run down the littany of season-ending injuries the Eagles faced, but what this team has accomplished without its MVP quarterback, its Hall of Fame left tackle, its best linebacker, its all-pro returner and its top special teamer is nothing less than astonishing.
Nick Foles is their quarterback and they're in the NFC Championship Game.
Think about the last month.
They came from behind in Los Angeles to beat the Rams after Wentz got hurt. They beat the Giants on the road. They beat the Raiders to clinch No. 1 seed. They "upset" the Falcons in a conference semifinal playoff game.
For this football team to be one home win away from the Super Bowl after all it has been through speaks volumes about Pederson. He's guided this franchise through adversity that would have crushed some locker rooms, and he's done it in his second year as a head coach above the high school level.
Pederson found a way to get 53 guys to believe in themselves even when very few other people did. And they returned the favor by consistently playing smart, physical, disciplined football for him no matter who the opponent, no matter what the score, no matter how long that Injured Reserve list grew.
This has been a masterful year for Pederson, and anybody who can't see that just isn't looking very hard.
