I dont see why the Ducks would want to push for Robertson when they are going to have a plethora of young forwards. And nonetheless retain salary on Gibby.

In addition, no accounting for Samsonov whose RFA rights are valuable in a trade.
Not really seeing the value of adding Gibson anyway, it is totally hit and miss as to whether he will perform better than Samsonov. Last two cups have been won by goalies who are not considered elite so Samsonov and Woll are just as good as anyone.

Gibson has already publically shot down a trade to Toronto so nothing else matters
