You're oversimplifying it, attributing all of their success to those moves. Do you honestly believe that if we traded any 3 of our current defensemen for those 3, we'd be legit cup contenders? We had Mikkola on this team, and we still fell short to Tampa. We have more issues than just the defensemen.
You could be right, but there's definitely something off with Mika that started last year and has only gotten worse. Maybe at this point, he would welcome a change of scenery. If we trade away his BFF, he might be even more inclined to move on.
I don't know what's in his head, but if we automatically assume he will veto any trade, then we might as well not even discuss it.
