"I understand we have two guys who need to be signed, and that can have big effects on our (NHL salary) cap situation moving forward, and our boss has to deal with that," Krug said. "Of course I wish there was dialogue and some sort of call or something like that. It's just nonexistent.
"I've put together a resume I'm very comfortable with and happy about. And trust me, I'm not saying I feel disrespected or anything. It's just part of the situation."
Krug told ESPN.com he would consider taking less money to stay with the Bruins.
"I think something could be worked out both ways," he told NHL.com
Krug led Bruins defensemen with 53 points (six goals, 47 assists) in 64 games last season and was second among NHL defensemen during the Stanley Cup Playoffs with 18 points (six goals, 12 assists) in 24 games to help the Bruins reach the Stanley Cup Final.
He said entering the season without a new contract will serve as motivation.
"It's nothing that will affect me personally in how I play," he said. "If anything, it's just added fuel to the fire. ...
"You've got be patient and try to do your part. Be a soldier."
Krug said the bitterness of losing Game 7 of the Cup Final to the St. Louis Blues on June 12 was tempered shortly afterward when his daughter, Saylor Harper, was born.
"I don't think you ever forget the disappointment of losing in the Final that way," he said. "That's no secret. But I went from the lowest of lows to the highest of highs. I had my first kid four days later. Our daughter really relieved that sad feeling, that lull.
"No disrespect to my teammates, but that's probably the best thing that happened to me."
