With no big additions up front, the Bruins will likely head into the season with a second line of Jake DeBrusk, David Krejci and David Backes.
Max Pacioretty, Erik Karlsson and Panarin were all expected to be traded this summer with only one year left on their contracts, and Panarin remains the only one that hasn't been moved yet.
The problem here would be the fact that the Bruins would have to sign Panarin, Charlie McAvoy, Brandon Carlo and possibly Zdeno Chara to new contracts next summer.
