In Game 4 of the Eastern Conference finals against the Lightning in Tampa on Saturday, the Bruins' Milan Lucic submitted a nightmare shift at the worst time. With the score tied at 3 in the third period, a series of Lucic errors snowballed and resulted in Simon Gagne's winning goal.

When Gagne entered the right corner to track the rebound of a Teddy Purcell shot, Lucic went after him, which resulted in a slack defensive formation instead of the pack-it-in setup required on such plays.

So when the rebound of Gagne's shot skittered out to Victor Hedman, Lucic wasn't in place to fill the lane and get in front of the defenseman. Instead, Hedman's blast rocketed off Tomas Kaberle's left leg.
