Pietrangelo is literally first in the league in high danger scoring chances against, ten more expected goals against than Nurse in 15 more minutes of icetime.
Unless you think Theodore + Stone + Pacioretty + Lehner is worse defensively than Barrie + McDrai + Koskinen...
Pietrangelo has been not very good this year.
Same goes with Pelech who has more High Danger Scoring chances against and more expected goals against than Nurse in the same 5 on 5 playing time playing behind NYI instead of EDM.
The Islanders have been poor as a whole so raw numbers shouldn’t matter as much. Pelech’s regression numbers are still very strong this year and regardless, we already know what he is. He’s clearly better defensively than Nurse. Though they would fill different roles, so I’m not sure they’re directly competing for a spot.
Pietrangelo has been poor, but he’s already named to the team, and his track record is generally much better anyway so he’ll likely turn it around
