I don't think EDM will trade their first RW without getting exactly what they need (#1 goalie, Top D, Top 6 forward with a great 2-way games) and MTL don't have the pieces right now.
I don't think MTL concentrate on the RW right now considering that they already got Gallagher, Parenteau, Sekac, Weise, Thomas and Andrighetto.
If there's talks, i think Perron is the most likely to be move since Draisaitl might need a slow start on the left side like Galchenyuk did and they already got Pouliot, Hall and Perron on the left....and if the plan is to get Galchenyuk at center, they will need a LW
