The Bruins are enjoying a second straight day off the ice. They will have their first practice tomorrow at Ristuccia Arena in preparation for the Eastern Conference Final against Pittsburgh.

The coaching staff, however, is hard at work with their Pittsburgh pre-scouting. Claude Julien cited Pittsburgh’s depth as a primary reason for the Penguins’ success. They have two top lines that the Bruins must decide how to defend. It could involve splitting Zdeno Chara and Dennis Seidenberg, or keeping the top power pairing together to negate James Neal, Evgeni Malkin, and Jarome Iginla.

“We’ve got a few days here before we can even think about playing that first game,” Julien said. “We’ll see how that goes. Maybe it’s pairing. Maybe it’s separating. But we’ll have something in mind by the time this first game comes around.”

Pittsburgh’s most recent lineup:

Chris Kunitz-Sidney Crosby-Pascal Dupuis
James Neal-Evgeni Malkin-Jarome Iginla
Matt Cooke-Brandon Sutter-Tyler Kennedy
Brenden Morrow-Craig Adams-Jussi Jokinen

Brooks Orpik-Paul Martin
Mark Eaton-Kris Letang
Douglas Murray-Matt Niskanen

Tomas Vokoun
Marc-Andre Fleury

The Bruins do not know when Game 1 will take place. The schedule depends on when the Western Conference games conclude. Detroit will look to finish Chicago tonight. Los Angeles and San Jose play Game 7 on Tuesday. The Boston-Pittsburgh schedule will most likely not be released until the West games are over.
