When St. Louis Rams owner Stan Kroenke bought 60 acres of land in the outskirts on Los Angeles, Inglewood in particular, it pretty much ensured that the Rams would be returning home to L.A.
They made that move before the 2016-17 season, as they played their first season at the Coliseum while their brand new state-of-the-art stadium broke ground at the end of 2016.
The desire was to play three seasons at the Coliseum and then move into the new stadium before the 2019-20 season when it was completed.
It appears that is not going to be happening though, as the record amount of rain that Los Angeles saw this past winter delayed the finishing of the stadium by a year, via TheRams.com:
Unfortunately, Southern California experienced record-setting rain this winter. Despite bringing drought relief to the region, the rain fell during the mass excavation period of construction when no other work could proceed in wet conditions. As a result, we experienced significant delays and lost the better part of two months from early January into the beginning of March.
In the best interest of the project, we have decided to move the opening date to summer of 2020.
The Rams also had desires of hosting the Super Bowl in the new stadium in 2021, as a stadium is not allowed to host a Super Bowl in its first year after being opening. It they still want to host that Super Bowl then it would require the NFL to allow an exception to that rule.
This news also affects the Los Angeles Chargers, as when they decided to come to L.A. they reached a deal with Kroenke to share the new stadium.
