Mtl seem to have too much center short term and D is a crying need. Col could go all the way this year and Byram is still young for now. Plus: Drouin has a low cap for 4 more years at 5.5M. 24 years old. Chemistry with Mckinnon. Could be a good fit for him. Wouldn't have to be the main piece of a poor offense, meaning less pressure. Byram could become what Mtl really needs in D eventually. Col already has Makar in that chair. Minus: Mtl invest in a prospect again and lose a top forward for now. Col lose a potential top D prospect. What would need to be added to close this deal for Col to make that push to the Cup and for Mtl to get that missing piece in defense?
