This is the list of teams that Pesce will allow a trade to. His list is not a no-trade list. it is a ok-to-trade-to list, even though they are callled no-trade lists.
I do not see any reason why the Bluejackets would give up substantial assets for Pesce when they are up against the cap and have 30M+ tied up in Werenski, Provorov, Severson, Gudbranson, Peeke, Boqvist, Blankenburg and Bean, with Jiricek knocking on the door.
Remember, Pesce's goal here is to NOT get traded. The best way to avoid a trade is to put teams that have zero interest in giving up a big package to acquire you
Flames are in the same boat.
Pittsburgh, Seattle (if arbitration goes south with Dunn) and Washington would likely be happy to acquire Pesce, so having them on his ok to trade to list is a good way to give Carolina an avenue to move him.
