Twenty-five percent of this year's NFL division winners went from worst in 2017 to first in 2018, making it the 15th season in the last 16 years that at least one team has made that leap from the basement to the penthouse.
The Houston Texans and Chicago Bears were this year's big leapers, while two teams—the Philadelphia Eagles and Jacksonville Jaguars—also accomplished that feat in 2017.
And those quick improvements aren't recent anomalies. The majority of this year's playoff teams weren't in last year's postseason, and according to Charean Williams of Pro Football Talk, at least four teams coming off non-playoff campaigns have made the playoffs in a ridiculous 29 consecutive seasons.
