What happened: Dallas opened camp Thursday with Jason Robertson and Thomas Harley on the ice after separate offseason trade agreements never got completed. Robertson had been headed to Seattle in a sign-and-trade before agreeing to a one-year, $12 million deal, while a Columbus move involving Harley and Mavrik Bourque died when Zach Werenski used his no-trade clause.

Why it matters: Robertson led Dallas with 96 points last season and can reach unrestricted free agency next summer if no extension is in place by Jan. 1. Harley is beginning an eight-year extension as the Stars try to regroup after a first-round playoff exit that followed three straight trips to the Western Conference final.

By the numbers: Robertson has 490 points, including 213 goals, in 456 regular-season games and has played all 328 games over the last four seasons. His $12 million salary matches Mikko Rantanen for the highest on Dallas, while Harley starts an eight-year contract worth $84.69 million.

What to watch: The next question is whether Dallas revisits long-term talks with Robertson once league rules allow it after Jan. 1. Harley's camp role and the ripple from Bourque's departure will be early tells for how the roster settles.
