It would be a big mistake to trade Harris right now. He is already such a steady defenseman at such a young age, I prefer playing him right side than trading him.

We need leadership and Harris is a big leader, not only in the the lockeroom but also in the community. He is capitain material and he already is one of the best person in the NHL.

MTL trading pick 32th and 37th means no top goalie prospect, so not a step in the good direction
Taking the Goodrow contract is a step back, and you trade Evans lol
Carrick is great for the AHL team of the Ducks, and while Ylönen is better and cheaper than Comtois, I wouldn't mind a swap Comtois for Ylönen if that means Pezzetta isn't coming back
COL definitely decline, Edmundson value is at minimum right now due to his back and play last season
Now for the UFAs/RFAs, imagine thinking Fischer is better than Gallagher lol I hate Gallagher but Fischer is a fringe NHLer
No need of Domi & Killorn, that's a step back
So pretty bad OP in general

Why on earth would the Avs want to do that?

Tell me you do not understand hockey without telling me that you do not understand hockey

Buying Goodrow Out makes much sense than to pay that much to be rid of him.
