I believe so, he also gave a supportive reply on instagram to the Ducks making the trade for Cutter.
He coached Cutter: The Sporting Tribune
"Gauthier also spoke to former Duck Ryan Kesler, who was Gauthier’s assistant coach when Gauthier was playing for the U.S. National Under-18 Team. Kesler and Gauthier have spent the last two summers together in Michigan––where both of them live. Kesler was also represented by Overhardt during his playing career, another common bond."
“Obviously, it was a bit different (for him). He was finishing out his career there with family and kids,” said Gauthier. “But he said it would be a great place to start a young career. There’s so much stuff to do, the weather’s great. He had nothing but great things to say about it, so listening to him and seeing how well he’s done in his career, pretty excited to get things going there soon enough.”
It's really nice to hear that Kesler enjoyed his time here. He obviously would have preferred to stay in Vancouver now knowing the results but hindsight always provides a different perspective. It's really hard not to like Kesler. Absolute warrior and hopefully he can pass some of that spirit over to Cutter.
