I doubt it. From what it was reported due to the tax law in Russia Pilut could be making nearly twice as much in Russia than he would playing in the NHL. And it is more likely that he will be given a lot more playing time in the Russian league than he would as at best a third pairing defenseman with the Sabres. I like Pilut a lot. He is a good skater and a smart player but he is not better than Joki who has a similar style of game.
In a backhanded way losing a solid to good player like Pilut and not having it more than marginally affecting the unit is a sign that that unit has accumulated a good group of blueliners. A few years ago this unit was bereft a talent. Now it has a solid to good core. That's progress.
