So who wins 18 times in 22 games?
"A really good coach who has a really good quarterback and really understands the game," said Packers secondary coach Jerry Gray, who held the same position with the Vikings the past six years. "I think you have to be really, really lucky. But you have to be good, too. To me, when you call his stats out, they're like unheard of, especially in today's game.
"But when you look at Matt, he's a guy who is going to fly under the radar. He's not going to be arrogant about his stuff. He's not going to be arrogant about his record. He's like a lot of coaches, but I think he's a little different with his new-age approach than an older guy would be. And he gets players to really buy in."
In a league that's in its 101st season, only five other coaches have won more than 17 of their first 22 regular-season games.
George Seifert (20-2) was handed the keys to Bill Walsh's 49ers dynasty after it won Super Bowl XXII after the 1987 season. Paul Brown (19-3) dominated the upstart All-America Football Conference in the late 1940s before his Browns were absorbed into the NFL in 1950.
The other three were player-coaches in the 1920s. Guy Chamberlin went 19-0-3 with the Canton Bulldogs; Dick Rauch went 19-3 with the Pottsville Maroons; and George Halas went 18-2-2 with the Decatur and Chicago Staleys before renaming them the Bears in 1922.
