The 52-year-old said he has already schemed with Montgomery around adding more offense to the blue line, an area of improvement that Boston's new bench and the club's brass has talked about focusing on since the end of the 2021-22 season. One way to do that, Gruden stressed, was creating more movement in the offensive zone, particularly among the two defensemen along the blue line.
"We obviously talked about that stuff," said Gruden. "I do believe one of the points that [Montgomery] made, he wanted to get them a little bit more active but without losing that ability to defend. That's Boston's MO - you can still do both and grow on the offensive part to get the D more involved to get the puck to the forwards and take the ice when it's available, but not force it.
"I'm obviously very familiar playing against Boston, coaching in New York. It's exciting just to try to build on something that's already there with Jimmy's vision and the other staff. It's exciting. We're looking forward to that challenge."
It will help Gruden that he already has some familiarity with Boston blue liners Matt Grzelcyk, Charlie McAvoy, and Connor Clifton, all of whom came through the United States National Team Development Program during the time that he was an assistant coach there from 2011-15.
"There are a few players that I've crossed paths with," said Gruden. "I think anytime you get to work with young men, especially at that age, where they were at that point of their lives and their hockey careers, you hopefully can leave a good lasting impression - which I hope I did that.
"Even when I see them around, when we cross paths in the rink, I always say hi and vice versa. It's exciting to work with a few of them that I've already crossed paths with and to keep building on where they're at and move forward with it and have fun with it."
Gruden said he always aims to impart upon those he coaches what he learned during his own career, which began with the Bruins when he was drafted by the Black & Gold in the eighth round of the 1990 NHL Draft out of Ferris State. After playing 92 games over parts of six NHL seasons with Boston, Ottawa, and Washington, Gruden transitioned to coaching with the USNTDP, helping Team USA to gold medals at both the 2012 and 2014 U-18 World Junior Championships.
He then went on to spend three seasons as a head coach in the OHL, one with Flint and two with Hamilton, the latter of which he led to a Robertson Cup championship in 2017-18.
"I have no regrets for my playing career. You can't change that. But I do believe it gave me the opportunity to still play 10 years in a lot of good leagues," said Gruden, whose professional career spanned the NHL, AHL, and IHL from 1993-2004.
"Again, of course, every kid, you start in the NHL, you want to play in the NHL your whole career. Doesn't always work out that way. I think it's how you handle it and how you can learn from it. I think it's made me appreciate the game that much more and put me in this position.
"I've coached this long now and to bring that to someone - these pro hockey players are very proud players. They are very good at their craft and they always want to learn to get better. That's the exciting part.
"But I have no regrets as far as my playing career. I think it's helped me, my path, with the adversity to get to where I am now. It's very exciting. It's always a challenge; nothing's easy, but you've got to work hard at it."
