NBA trade tracker: Grades and details for every offseason deal in 2021

Get a glimpse into the Lakers new Big 4 (1:17)

Take a look into what the Lakers could expect from LeBron James, Anthony Davis, Russell Westbrook and Carmelo Anthony this season. (1:17)

NBA trade season got off to an early start in the summer of 2021, with the Boston Celtics and Oklahoma City Thunder swapping former All-Stars. As the NBA moves past the 2021 NBA draft in July and toward 2021 free agency in August, expect there to be many more deals.

With multiple superstars signing contract extensions over the past year, the free-agent class of 2021 isn't as star-studded as previously expected. Will that mean teams looking to shake up their roster will try to make a trade for superstar players, like we've seen in past years with James Harden going to the Brooklyn Nets and Paul George going to the LA Clippers? If so, we'll have a rundown of those deals -- plus every other trade that gets made -- right here, including grades from ESPN's Kevin Pelton.
