In the last three games, the Bruins have now lost six players – including two more tonight — through various injuries and an imminent suspension. But not only did the B’s avoid slipping too far backward, they continued to trudge ahead. And after coming from behind to beat the Penguins on Saturday, they leapfrogged both Pittsburgh and Montreal to jump back into first place in the Eastern Conference with a 5-2 victory over the Toronto Maple Leafs at the Air Canada Centre. The B’s got second period goals from Carl Soderberg, Torey Krug and Kevan Miller and then, after the Leafs got to within a goal 37 seconds into the third, Jarome Iginla sealed it with 4:00 left. Patrice Bergeron added an empty netter to finish off the scoring.
