‘Carter Hutton played over his head last year. He wasn’t going to post a .931 save percentage again. But he was a sensible, short-term veteran signing by GM Jason Botterill to pair with riser Linus Ullmark. They’ve combined for a .919 SP as a tandem so far this season. Last season, Sabres goalies posted an aggregate SP of .904. Hutton and Ullmark haven’t been Vezina-Trophy-caliber elite, but they’ve been good, and “good” is a significant upgrade. The team’s 5-on-5 SP has combined with a shooting percentage north of eight percent to give Buffalo its highest PDO (puck luck indicator, essentially) in the statistic’s 12-year existence. Luck favors you when your goalies stop the puck.’
