Those are some of the areas where the Senators hope Boucher can make them better.
Boucher, 45, had coached Bern in Switzerland the previous three seasons after coaching the Tampa Bay Lightning from 2010-13. He went 97-79-20 and led the Lightning to the 2011 Eastern Conference Final.
"He's a very passionate and intense guy which I think, for the type of team that we have, is going to fit very good," Dorion said. "He's a young mind, we have a younger team, and I think what he brings to the table and the way that he believes things work is going to match up with everything that we have in the room."
The Senators' room consists mostly of a homegrown core that includes defenseman Erik Karlsson and forwards Mark Stone, Mike Hoffman, Jean-Gabriel Pageau, Curtis Lazar and Zack Smith. Center Kyle Turris should be healthy after an ankle injury limited him to 57 games, and forward Clarke MacArthur is expected back after a concussion sidelined him the final 78 games of last season.
Though the Senators will have a bit of a new look up front, the goaltending and defense remain the same. Goalies Craig Anderson and Andrew Hammond return with Karlsson leading a group of defensemen that includes veteran Dion Phaneuf, entering his first full season with the Senators, Marc Methot, Cody Ceci (a restricted free agent), Mark Borowiecki and Chris Wideman.
"You have the players that represent your style and I think we have that," Boucher said. "Speed up front, transitioning defensemen, good goaltender, the possibility of improving the defensive side of it with structure, which I think I'm known for."
