What happened: Fourth Period noted potential movement on a swap sending restricted free agent Jason Robertson to Detroit in exchange for Larkin. Robertson turned down an eight-year contract extension worth $15 million annually from Dallas. Larkin formally requested a move from Detroit on June 4 before expanding his trade preferences in July.

Why it matters: A swap between the franchises would alter the core leadership of both rosters ahead of the upcoming 2026-27 campaign. Kypreos reported in late June that Dallas emerged as the frontrunner to acquire Larkin, who currently serves as Detroit's captain. Trading Robertson would also clear a major salary cap impasse for Dallas as the organization navigates his unsigned status.

What to watch: Watch whether Dallas and Detroit finalize a direct transaction or involve a third franchise ahead of NHL training camps for the 2026-27 season.
