PORTLAND, Ore. — In the wake of recent postponed NBA games in Los Angeles, the Miami Heat as of Saturday remained on schedule to travel and play there on Monday night against the Los Angeles Clippers and Wednesday night against the Los Angeles Lakers. Amid that schedule, coach Erik Spoelstra said ahead of Saturday night’s game against the Portland Trail Blazers at Moda Center that concerns about his team’s preparations pale in comparison to the fires that have burned communities to the ground and displaced tens of thousands. “We’ll be able to handle whatever we need to handle,” Spoelstra said after his team’s morning shootaround.
