Sami has a Fenwick of 52%, meaning that the Ducks take 52% more shots than the other team when he's on the ice. That's the highest out of any player on the team.
Sbisa is one of the worst players in the NHL. I'm serious.
That isn't what it means at all, and there's a reason when Sami is on the ice the team puts more shots on net. It has to do with the situations Sami is put on the ice for, to begin with. If a player is put on the ice, primarily, in desirable offensive situations, that's exactly what the stats will show.
Don't mistake Sami's role with him dictating the play in that fashion. Those stats show that Boudreau shelters Sami, and tries to get him on the ice in favorable conditions.
And Sbisa isn't even close to one of the worst players. Defensively, he's certainly better than Vatanen right now, and capable of handling more defensive responsibilities. Sbisa certainly has his faults, but as a defenseman I absolutely trust him to be able to play a less sheltered role, and play more minutes, than what Sami has shown. I don't know what the future holds, but right now? I have no problem right now with Sbisa getting the minutes instead of Sami. If Sami can prove himself the better defenseman, then that will change. As it is, I think some of that also comes down to the opposing team, because I think Sbisa is a better choice against some teams, and Sami is against others. Lindholm doesn't belong in this discussion, because Sbisa wouldn't be taking his minutes.
