There isn't a particular glaring need in the system, the Ducks are flush with young talent at all positions and really just need these top young players to start realizing their potential. There is a lack of high end scoring at the moment, but trading our most proven young offensive player does the opposite of addressing that need, unless in a package for an elite producer.
Once again need to understand that these "rumors" started from pure speculation that Zegras might be shopped, which has been refuted by more reputable sources. Anaheim has no reason or desire to trade him unless there is some sort of elite talent available for which they are building a package. These offers where teams throw together a first and spare parts, have zero intrigue from the Ducks side, does nothing but make a bad team worse when they are trying to do the opposite.
