Where the Sabres faltered, Housley said, was in their attention to detail. Boston's first three goals were all scored by an unchecked man - Zdeno Chara shot alone on the rush, Ryan Donato buried a 2-on-1 feed on the power play and David Pastrnak scored alone at the back door in the second period.
"These are things just about our checking detail of our game," Housley said. "It needs to get better, or we're going to have results like that."
