What happened: Los Angeles acquired Myles Garrett, Trent McDuffie and Jaylen Watson before Aaron Donald ended a two-year retirement. The defensive overhaul followed an NFC championship game loss to Seattle, while Matthew Stafford returns for his 18th NFL season as the reigning MVP.

Why it matters: The Rams last won the championship at SoFi Stadium five years ago after a comparable all-in push. Super Bowl LXI returns to SoFi, creating another chance to win the title on their home field. After Melbourne, Los Angeles hosts the New York Giants without a bye before road games at Denver and Philadelphia.

What to watch: Los Angeles opens against San Francisco on Sept. 10 in U.S. time zones at Melbourne Cricket Ground. Donald's availability is the immediate lineup question after two seasons away from football.
