The Kings needed a backup goaltender after trading Martin Jones to the Boston Bruins in the deal that brought Milan Lucic to Los Angeles. So, the Kings signed Jhonas Enroth to a one-season, $1.25-million contract Wednesday. Enroth played 50 games last season, including 37 with the Buffalo Sabres. He also played for the Dallas Stars. Overall, he was 18-26-2 in 2014-15. He’s not likely to play anywhere near that much as Jonathan Quick’s backup with the Kings next season.
