"His 200-foot game, obviously he's gotten stronger, gotten quicker," Lightning assistant GM/director of player development Stacy Roest said. "His offensive play, his defensive play. We just love his all-around 200-foot game, all three zones. He's a good player and a good prospect."
Gauthier is also a prospect with a bit of a swagger. Making the World Juniors team is just his latest accomplishment.
Last season he was tied for second among QMJHL playoff scorers with 25 points (14 goals, 11 assists) in 19 games to help Drummondville win the league championship.
Then, during training camp with the Lightning, he got into three preseason games.
"You earn your opportunity for another opportunity, and that's what he kept doing," Roest said. "He had a good camp. He got nicked up a little bit during camp, so he missed a few practices, and then he gets in one game, and it's an opportunity to earn another opportunity, and that's what he just kept doing at camp.
"Very excited, very happy for how he played there. And then he goes back to junior, and you're excited ... when he comes and shows that well and plays that well, it's exciting for the Lightning for sure."
Another step will be showing he can handle the uptick in competition at the World Juniors.
"Anytime your prospects get a chance to play for their country ... with the elite group of players that are there, it's a special moment," Roest said, "and it's going to help you with your belief in your game and where you're at in your career.
"For him, he's earned it. He's had a great couple seasons. He's played really well this year. And I think it's huge he gets a chance to play for Canada, and I know he'll do a great job."
Now he just has to keep moving to have success at the WJC, and eventually that could carry him to the NHL.
"The games in which I have more success are when I’m moving my feet, when I’m in motion," he said. "That's really the key. When I play with pace, when I move my feet, when I overtake the defenders, that's when I have success. If I don't do that, I have good games but not excellent games. It's getting back to basics, making sure I have the mentality to move my feet and be in motion."
