The Winnipeg Jets tried to re-sign rental center Paul Stastny to a contract once he became a free agent, but he spurned them to sign a three year deal with the Vegas Golden Knights, the team that defeated them in the WCF.
He pulled a Kevin Durant, without, y’know, being the star of his team. The old, if you can’t beat em, join em. In all seriousness, they probably offered him more money.
Or, you know, it’s Vegas, baby. Factor in that they were in the Stanley Cup Finals as an expansion team, and Stastny had plenty of reason to like Vegas over Winnipeg.
