The Kings and Jets continued a dialogue for roughly two months, but Byfuglien ended up signing a five-year, $38 million contract extension with Winnipeg on Monday.
According to one league source, if Byfuglien was unable to sign an extension with the Jets, "it sounded like he would have ended up in Los Angeles; they're going all-in."
It's unclear what type of deal the Kings and Jets had discussed, but that's a moot point now.
The Kings will shift their focus onto other defensemen, including Vancouver's Dan Hamhuis and the New York Rangers' Keith Yandle, whom Lombardi has long coveted, among others.
Hamhuis is returning to action Tuesday from a concussion and facial surgery. He owns a full no-trade clause and will have to approve any deal the Canucks attempt to complete.
As much as the Kings would like to add another top-four defenseman, they're also keeping tabs on the available forwards leading up to the Feb. 29 trade deadline.
The Kings are believed to be eyeing Jets captain Andrew Ladd, who owns a limited no-trade clause, and Calgary Flames right wing Jiri Hudler.
