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.
There's no discouragement in that room. There's no issues there at all to be honest with you. It's more about, 'Hey, it's opportunities for players.'
