The Bruins defeated the Flyers 6-3 on the back of elite goaltending in a game where the scoreboard lied about which team was better. Boston controlled only 41% of expected goals at 5v5, a 59-41 disadvantage that made this a heist in reverse: the Flyers dominated the play, but the Bruins' goaltending turned the game.

J. Swayman was the difference. The Bruins netminder stopped 33 of 36 shots for a 0.917 save percentage, finishing 1.81 goals above expected. S. Ersson conceded 2.41 goals above expected on a 0.750 save percentage (15 of 20 stops), while D. Vladar (6 of 6, +0.78) was perfect in relief.

The Flyers created the better chances. They generated 11 high-danger scoring opportunities to Boston's 4, and their overall xG advantage (4.81 to 3.37) reflected consistent pressure—59% of the slot action was theirs. But Boston was ruthless when it mattered. The Bruins converted 2 of 4 high-danger chances for 50% efficiency and scored 5 times on 21 rush attempts, turning transition moments into goals.

Matvei Michkov's wrist shot from the doorstep midway through the third period cut the deficit, but by then Boston had already run away. F. Minten (1G, 2A in 15:00) and C. Mittelstadt (1G, 2A in 14:54) led the charge, while A. Peeke's 2 assists in 20:03 reflected Boston's dominance despite the underlying metrics.

This game belonged to whoever possessed the net. Swayman made sure it was the Bruins.

The model calls this a toss-up: Philadelphia at 2.5 goals per game, Boston at 2.4, Flyers favored at 51% win probability. That's as close to even odds as modern hockey gets.

Boston's trajectory suggests otherwise. The Bruins are 8-1-1 over their last 10 games and rolling, while Philadelphia sits at minus-19 goal differential in that same stretch. That form advantage, though, doesn't tell the whole story.

The underlying data favors the Flyers. At 5v5, Philadelphia generates 51.0% expected goals compared to Boston's 47.0%—the fundamental play belongs to Philadelphia. Corsi tells a subtler tale: Boston edges Philadelphia 49.0% to 48.0%, a gap so thin it rounds to irrelevant.

Here's where things get messy. Boston's PDO sits at 1.023—a mark indicating they're running hot and some regression is coming. Philadelphia's 1.008 PDO suggests they're closer to sustainable performance. The Bruins are banking on luck, and luck doesn't travel well.

J. Swayman is on a back-to-back, a wild card in Boston's favor if they start a backup or a liability if Swayman plays tired.

Philadelphia's Owen Tippett is the most dangerous weapon on the ice. At 0.88 expected goals per 60 minutes, he's generated 19 goals with 18 assists and owns 2 high-danger goals on a 12.1% shooting rate. Christian Dvorak (0.81 xG/60, 12 goals, 21 assists, 3 high-danger goals) gives the Flyers a secondary threat operating at 11.2% shooting.

Boston counters with Viktor Arvidsson, whose 1.04 xG/60 leads all forwards in play here. Arvidsson has 18 goals, 24 assists, and 2 high-danger goals on 13.0% shooting—elite, translatable production. Tanner Jeannot (0.75 xG/60, 6 goals, 14 assists, 2 high-danger goals) operates at 8.3% shooting.

The Flyers own superior even-strength play and a goaltender advantage if Swayman doesn't start. The Bruins own superior form and a player in Arvidsson who can single-handedly shift momentum. The model's coin flip reads correctly.
