Really wasn't any rumor of him moving at the deadline, that's an off season move if anything.
Verbeek was pretty candid on the topic. He said look around the league at all these good teams who can never figure out their goaltending. When you have someone who has proven to be a workhorse, should be in no hurry to give them up.
Plus the Ducks used up their retention slots in the Lyubushkin and Edmonton (Henrique/Carrick) deals, just likely weren't any teams able to take on Gibson's full 6.4M right now.
Could see it finally going down by the draft though, if Dostal finishes strong. Give him more of the reigns and pair him with a cheaper 1B guy.
