"I think [being reunited with Boucher] is going to be great for myself," Hoffman said. "He knows how to work with me. He's a great coach. He's going to be great for all the players in Ottawa and I'm really looking forward to working with him.
"He kind of set me on the right road (in Drummondville). I came in there as a young player and I needed to learn a lot. He teaches you a lot about on-ice and off-ice behaviors. I give a lot of credit to my career on his coaching and what he did for me in Drummondville.
"Back then we never realized we're both going to be with the same NHL team one day, so it's a pretty cool story."
Under coach Dave Cameron last season, Hoffman ranked sixth among Senators forwards in power-play ice time but led them with nine power-play goals and was fourth with 13 power-play points.
"The thing that's exciting about Mike Hoffman is he's going to play for a coach, without divulging too many secrets, [who] simply adores him," Dorion said. "We're excited that they can grow together, that Mike just won't accept scoring 30 goals, but his game can just be even more rounded. We're excited about how Guy told me he is going to use him on the power play, and it can only be more fruitful for our team. He can be even more productive.
"We've invested in Mike Hoffman for all these years, and for us today, getting to sign him and buying three years of [unrestricted free agency] and getting him in his prime in what we feel is a very good contract -- and I know Mike is happy with the contract -- it's just a great day for the organization. I actually hugged (assistant GM) Randy Lee today."
Dorion's next job is getting restricted free agent defenseman Cody Ceci under contract.
"The only date that matters is Oct. 12 (the regular-season opener against the Toronto Maple Leafs) and I can assure you that Cody will be playing for us on Oct. 12," Dorion said.
