League sources told ESPN and NFL Media on Saturday night that Detroit will receive two first-round picks and a third-round selection in the blockbuster trade. According to the outlets, the Lions will get a third-round pick in 2021, a first-round choice in 2022 and another first-rounder in 2023.
The trade, which can't be made official until the start of the new league year in March, will be the first exchange of former No. 1 overall picks in the common draft era (since 1967). Stafford was taken with the first-overall pick in the 2009 draft, while Goff was selected No. 1 in 2016.
The 32-year-old Stafford will leave the Lions as the team's all-time leader in every passing category. He ranks 16th in NFL history in career passing yards (45,109) and passing touchdowns (282).
Stafford is No. 4 in league history in passing yards per game (273.4), trailing only Patrick Mahomes, Drew Brees and Andrew Luck. He also is fourth all time in completions per game (23.6), behind only Brees, Mahomes and Matt Ryan.
Goff, 26, departs Los Angeles after five seasons, including four under Rams head coach Sean McVay. Goff, who posted a 42-27 record with the Rams, won back-to-back division titles and an NFC championship in his first two seasons with McVay at the helm.
The Rams gave Goff a four-year, $134 million extension after he guided the franchise to a Super Bowl appearance in the 2018-19 campaign.
The Rams' offense, however, never looked the same following a 13-3 loss to the New England Patriots in Super Bowl LIII that season, as Los Angeles fell from a top-scoring offense to an average unit the last two seasons.
Goff recorded 18,171 passing yards, 107 touchdowns and 55 interceptions in five seasons with the Rams.
The Lions are scheduled to face the Rams next season at SoFi Stadium.
