MIAMI — The Portland Trail Blazers spent the 2023 offseason acting as if the Miami Heat didn’t exist, at least when it came to soliciting trade offers for since-dealt guard Damian Lillard. Friday night at Kaseya Center, the Blazers could not deny the reality of the Heat very much taking care of business, with Erik Spoelstra’s team pounding Portland 142-82 — the most lopsided victory in the Heat’s 36 seasons. “There was a professionalism from our part and an energy and an intentionality,” Spoelstra said.
