Murphy, 30, was traded from the New Jersey Nets to the Golden State Warriors last week, but was then bought out of his contract. Once a free agent, he spent the next few days mulling several offers, most notably from Boston and Miami.
Murphy, a 6-foot-11, 245-pound former first-round pick out of Notre Dame, averaged 14.6 points and 10.2 rebounds last season with the Indiana Pacers. With the Nets, though, the New Jersey native averaged just 3.6 and 4.2 this season. He played in just 18 games with New Jersey.
