A falloff is coming for a handful of NFL teams.
The law of averages indicates that some of this year's unluckiest teams will inch back toward the mean next season, while some of the luckiest won't have the same fortune again. The proof is often in the playoff bracket, where each conference again sported at least two new arrivals that displaced past contenders.
Looking ahead to 2020, some teams will take a step back for a variety of reasons. Critical projection tools like one-score records and turnover differential tell an important story, as do simpler outlooks surrounding roster talent, the state of a team's division and salary-cap and draft scenarios.
