Matthew Stafford officially joined the Los Angeles Rams as the NFL's new league year began on Wednesday.

Stafford was traded to the Rams from the Detroit Lions, who received quarterback Jared Goff and multiple draft picks from Los Angeles. Detroit received a third-round draft pick in 2021 and first-round picks in 2022 and 2023.

The swap of former No. 1 picks represents a significant shift for both franchises. Goff took the Rams to the Super Bowl after the 2018 season.
