What happened: The Pittsburgh Penguins are assessing early concerns, including defensive mistakes and inconsistent goaltending from Arturs Silovs. Following Wednesday's trade of Filip Hallander to the Edmonton Oilers, assistant general manager Jason Spezza noted the team acquired 26-year-old defenseman Spencer Stastney to add versatility and mobility.

Why it matters: Pittsburgh's sluggish start features quiet early production from Sidney Crosby as the team attempts to stabilize its roster. In a corresponding organizational move, prospect Atley Calvert earned a two-year entry-level contract after filling multiple roles for the AHL affiliate.

What to watch: The Penguins seek to resolve their defensive lapses in upcoming preseason action.
