What happened: Steve Yzerman has acquired Golden Knights forward Keegan Kolesar, adding a physical, Stanley Cup-winning bottom-six presence to Detroit's forward group. Vegas moved Kolesar in a salary-shedding deal, sending the same Cup-winning forward Keegan Kolesar out for draft-pick capital.

Why it matters: The addition gives Detroit a rugged, experienced depth piece as it builds toward the 2026-27 season. For Vegas, clearing Kolesar's cap hit opens roster flexibility to reshape the lineup this offseason.

What to watch: Watch how Detroit slots Kolesar into its bottom six and whether Vegas redeploys the freed cap space on further offseason moves.
