Andy Reid is 16-3 following an off week in his coaching career, of which Matt Nagy was a part from 2008-2017. But does that mean Nagy, as a former Reid assistant, has a path to enjoying the same success?
Nagy gave Bears players the entire week off following their Week 4 win over the Tampa Bay Buccaneers, a move that was not contingent on his team winning. The importance of rest for players and coaches alike is something he took away from his time under Reid.
"The rest is important and it's not always just physically, it's mentally," Nagy said. "It can be a stressful time whether it's week four or week 12 that you have it. So I think the rest is important, trust in your players and your coaches and in not doing too much."
To get a better sense of how much carryover there has been from Reid to his assistants following an off week, here's how everyone who worked under Reid and then went on to a head coaching job fared following the off week:
New York Jets
St. Louis Rams
Total record: 18-19
There's far more that goes into winning after an off week than experience coaching under Reid, of course. The quality of the team and quality of the coach count more than just being a Reid guy; Spagnuolo is 11-41 as a coach and led some atrocious Rams teams; Harbaugh is 97-68 and is a Super Bowl winner.
Under John Fox, the Bears were 0-3 after an off week, including 2017's loss to the Aaron Rodgers-less Green Bay Packers that was the clear beginning of the end for the veteran coach's short-lived tenure in Chicago. Marc Trestman was 1-1 after the off week, which included a different kind of loss (55-21) to the Packers that wound up helping to get him fired, too. Lovie Smith was 6-3 following an off week.
So what matters more than who a coach worked for is how good a coach is, and how good a team is. The Bears can be optimistic that Nagy is a good coach, based on how this team responded to that brutal Week 1 loss to the Packers and how well things have gone in the first four games of his nascent time in Chicago. And they can, too, be optimistic that the 2018 Bears are a good football team, based on the massive presence of Khalil Mack and an encouraging breakout game against the Bucs the last weekend in September.
Nagy and his coaching staff had an early opportunity to self-scout themselves during the off week, too, and while it didn't lend as much information as a self-scout during a later off week might, it still was beneficial.
"It doesn't mean that you're going to not change anything, but when you have that extra week it's so easy to go crazy and just start thinking you can start doing this, this and this and then all of a sudden this, this and this doesn't work," Nagy said. "I think it's really just a belief and trust system with the players, the coaches and then when you do come back like today, you have a food practice and you don't go through it slow motion, you go through it full speed."
