4. Vladislav Gavrikov
The area of the roster that the Los Angeles Kings are the deepest is on defense, and they are struggling to get everyone minutes. It wouldn't be surprising if this is the Kings' look to swap out a defenseman for a forward.
One of those players could be Vladislav Gavrikov and while he has been arguably the team's best defenseman, he is also set to be a free agent after this season. This season he has three goals and 17 assists with a +/- of +9.
Recently Elliotte Friedman with SportsNet noted that Gavrikov recently switched agents and typically this is an indication the player may be preparing to leave. However, Friedman wrote the Los Angeles Kings have optimism they can re-sign him and won't require a new contract extension to be competed before the trade deadline.
While pending free agents are often moved at the trade deadline, this is one instance that doesn't seem like it will be the case and that is why he is fourth on this list.
