So far this season the Bruins are 1-for-2 in building their top lines by integrating a newcomer into the established structure.

Free-agent signee Jarome Iginla has been a perfect fit for the right side of the David Krejci-Milan Lucic combo and that line has combined for 36 points.

However, trade acquisition Loui Eriksson hasn’t quite made the same sweet music with the duo of Patrice Bergeron and Brad Marchand. Eriksson’s return to the lineup against the Dallas Stars on Tuesday featured Bruins coach Claude Julien sticking the winger back with the Marchand-Bergeron combo even though the coach had given up on that a few games before the night Eriksson was injured. Once again, that group gave the Bruins nothing on the score sheet against Dallas.

While Eriksson was out for five games with a concussion, the coach often lamented the fact that Reilly Smith, Bergeron and Eriksson had just started to click and created some scoring opportunities against the Sabres before the John Scott hit derailed that trio’s progress. In explaining his decision to give Marchand-Bergeron-Eriksson a second shot, Julien expressed a desire to see if Carl Soderberg, Chris Kelly and Smith could find the chemistry they flaunted during the preseason. In the back of his mind, though, he has to also be thinking “this is what we brought Eriksson here to do: be the second-line right wing.”
