Several teams made strong pushes for Andersen – including a late bid by the New York Knicks – but Andersen wanted to return to a roster core and franchise that will move on without LeBron James.
The Heat have provided a career renaissance for Andersen, who signed there as a free agent in 2012. Andersen has played 12 NBA seasons, including stays with Denver and New Orleans.
Andersen, 36, has been an important frontcourt presence for the Heat. He shot 64 percent this past season while averaging 5.3 rebounds and 1.3 blocks, in nearly 20 minutes per game.
