Jonathan Toews carried the puck down left wing and dished a cross-ice pass to Seabrook, who fired in a shot from the right circle before goalie Steve Mason could slide across the crease.
Patrick Sharp and Bryan Bickell scored 59 seconds apart late in the second period, and Viktor Stalberg also connected in regulation for Chicago (18-0-3), which won its eighth straight overall and has earned 39 out of a possible 42 points this season.
That's a really tough thing to play through; when you finally are thrown out there, the game is fast, intense, every single play matters, you've got to find a way to play through that and make smart plays. So it's a huge testament to [Vermette] and some other individuals in our locker room that are putting their own ego, their own wants and needs aside, and are ready for those opportunities when they do come.
