The Kings’ Stanley Cup Era, which peaked with their championships in 2012 and 2014, ended around the same time as the Ducks’ Pretty Good Era, a stretch highlighted by their 2007 Cup win and trips to the Western Conference finals in 2015 and 2017. The two Southern California teams then began synchronized rebuilds, each waiting a year or so too long to upgrade their speed and skill and missing the playoffs together in 2018-19 and 2019-20. It took special skill to miss out last season, when the NHL expanded the playoff field from the usual 16 to 24, but they managed to slide under that low bar.
