Kristaps Porzingis

Celtics president of basketball operations Brad Stevens released a statement Monday after making the Kristaps Porzingis and Jrue Holiday trades official.

Dan Titus provides fantasy basketball analysis for the latest NBA offseason news, trades, Ace Bailey and Cooper Flagg.

Boston, Atlanta and Brooklyn are finalizing a trade that will send Kristaps Porzingis to the Hawks, Terance Mann to the Nets, and Georges Niang to the Celtics, sources told ESPN's Shams Charania.

Some teams have wasted no time making moves, with the Celtics reportedly trading two starters in the first two days of the offseason.

Charania's report indicated there is a lot of "uncertainty" in Boston with Jayson Tatum (Achilles) set to miss at least most of next season. The 39-year-old Horford could opt to sign elsewhere to try and win another ring, since the Celtics may not be able to put together a strong enough team to make that happen this season. Horford would play a significant role if he remains in Boston now that Kristaps Porzingis is in Atlanta. If he chooses to leave, multiple contenders should have plenty of interest.
