Kings general manager Dean Lombardi scratched one final item off his summer to-do list Wednesday when he announced the team agreed to terms with left wing Dwight King on a new three-season contract. King, a restricted free agent, was the last of the KIngs’ unsigned players. The Kings are the only team for which King has played during his NHL career. He has 24 goals and 30 assists in 157 games with the Kings over four seasons. He helped them win Stanley Cup championships in 2012 and ’14. He set career highs with 15 goals and 15 assists in 77 games in 2013-14. In addition, he had three goals and eight assists in 26 playoff games.
