Penguins coach Dan Bylsma is concerned enough about his team's work that he reconstructed three of his four lines at practice Sunday, leaving only the Matt Cooke-Max Talbot-Tyler Kennedy unit intact.

The other combinations are Chris Kunitz-Sidney Crosby-Mike Comrie, Eric Tangradi-Mark Letestu-Evgeni Malkin and Mike Rupp-Craig Adams-Pascal Dupuis/Eric Godard.
