How the NBA trade deadline sets up 2020 free agency

The 12 trades that teams made in the 48 hours before the 2020 NBA trade deadline is a preview of what to expect this offseason. With salary-cap space in short supply, the transaction game will have to come more by trades than lucrative free-agent contracts.
