Maybe that was the buy signal we were looking for with the Preds when they dominated the Bruins 4-0 at Bridgestone Arena on Wednesday night? After five losses to open the season, Nashville finally stopped being passive, forechecked and backchecked with aplomb, while Juuse Saros stepped up with his first shutout of the season in goal. Meanwhile, the Blackhawks are suddenly shipping too many goals, and Petr Mrazek (3.24 GAA, .887 saves) in the nets has had a very unremarkable start to his season, unfortunate for Chicago as it might need a big effort in the crease to stall the current slump.
