In a Game 7 of any series, let alone the Stanley Cup Final, every decision is held under the proverbial microscope. With the St. Louis Blues leading 1-0 in the dying seconds of the first period, the Boston Bruins made a bone-headed mistake in the final minute. Alex Pietrangelo would score an uncontested goal just before first intermission, and it can be credited to Brad Marchand calling for a line-change.

WHY?! Talk about the worst possible timing.

This decision by Brad Marchand will live in infamy in Bruins history if they go on to lose this one.
