PORTLAND, Ore. — The sale of the Portland Trail Blazers from Paul Allen’s estate to Tom Dundon’s group was unanimously approved by the NBA Board of Governors yesterday. In 1988, Paul Allen bought the Portland Trail Blazers for $70 million. After he died at the age of 65 in 2018 from complications of non-Hodgkin lymphoma, his sister, Jody Allen, took control of the Blazers and Seattle Seahawks. A period of poor performance endured for three seasons since the 2021-22 NBA season.
