Who knows what happens if that trade doesnt happen.
Maybe Subban doesnt suffer the same injuries, maybe he doesnt struggle out of the gate like he did in Nashville because he wouldnt be shook, he did play much better as season went on and into the POs, not to mention being a Norris nominee the following year.
Maybe we move him after that. Nashville were able to move him to Jersey, so onviously his contract was still movable.
Who knows. We have seen countless times a player perform a certain way on one team and be very different on another team.
