Robertson isn't going to be cheap. From Friedman:
"According to multiple sources, the Seattle Kraken were given permission by Dallas to talk to Jason Robertson, and offered him approximately $15 million per year on a eight-year deal — but the offer was declined.
Neither the Stars nor the Kraken agreed to comment, nor did Robertson’s representative, Andy Scott.
It’s believed the two teams had worked out some kind of trade before the permission was granted, apparently including Seattle’s first-round pick — seventh overall in Friday’s draft.
It’s hard to say what’s next for the Stars and their 40-goal winger, who are believed to be at least $2 million apart per season. Their top contract is Mikko Rantanen at $12 million per year, and the hope was Robertson would come somewhere around that number.
Robertson is a restricted free agent as of July 1."
