Detroit's 5-4 win understates their control. The Red Wings held 58% of expected goals (4.70–3.42), converting a tight scoreline into decisive underlying advantage.

Detroit's edges compound. They controlled 10 high-danger chances to Boston's 6, and generated superior efficiency—0.077 expected goals per shot versus Boston's 0.050. The Red Wings punished the rush: 5 goals on 29 chances, a rate that separates contenders from pretenders.

Goaltending magnified Detroit's advantage. J. Swayman surrendered 1.6 goals beyond his expected performance on 18 saves, a catastrophic underperformance. J. Korpisalo entered in relief and posted a shutout—saving 1.3 goals above expectation, steadying Boston too late. Meanwhile, J. Gibson backed Detroit with 34 saves on 38 shots.

Neither team capitalized on rebounds despite attacking the net. Detroit created 8 rebound opportunities; Boston 3. This restraint in chaos kept the margin narrow, even as Detroit's quality and volume proved too much to overcome.

The model projects a 2.4–2.6 game with the Red Wings at 54% win probability. This is as close to a pick'em as you'll find.

Detroit enters on a downswing: -7 goal differential over its last ten games. But the underlying metrics run ahead of recent results. The Red Wings lead in expected goals percentage (49.0% to 47.0%), while Corsi% is deadlocked at 49.0%.

Boston's PDO of 1.023 signals overperformance. That number will regress. Detroit sits at 0.985, suggesting variance is working against it—not an insurmountable gap, but meaningful over sample size.

The Bruins' forward depth hinges on Viktor Arvidsson, who generates 1.04 expected goals per 60 minutes and owns 18 goals against 24 assists on the season. His shooting rate of 13.0% is elevated; his 2 high-danger goals keep him operational. Tanner Jeannot creates at a lower rate (0.75 xG/60) with 6 goals and 14 assists, though his 2 high-danger goals suggest he's getting to the right spots. His 8.3% shooting percentage leaves upside.

Detroit leans on Alex DeBrincat, whose 0.88 xG/60 and 17 goals—28 assists split puts him in constant threat range. His 9.0% shooting rate is sustainable. Marco Kasper, at 0.81 xG/60 with 7 goals, 8 assists, and 1 high-danger goal, is the secondary punch; his 6.1% shooting shows lower variance.

Boston's defensive weakness is Elias Lindholm. Detroit's is Axel Sandin-Pellikka. Neither team is getting high-danger production at the rate you'd expect for a close game—both are running 0% on both high-danger and rebound goals. That says either elite goaltending or underperformance up front. The model gives Detroit a slight edge at 54%, reflecting better underlying metrics despite worse recent luck.
