Total snipe.
I gotta give credit to Spooner for his actions leading up to the goal.
1) After Chara tried to exploit a seam in the offensive zone, Spooner was the guy that roatated back on D and helped McAvoy interrupt the rush.
2) Got the puck to McAvoy who has this amazing skill to make a long pass to an open guy who can do something
3) Drove the net while DeBrusk was going wide, forcing defenders to play him and give DeBrusk the opportunity to go high, near side.
edit: They changed it. Spooner/McAvoy with the assists.
