Morning Skate: Lightning lock up Tyler Johnson to 7-year deal

BRIGHTON, Mass – There is little question that youth is going to continue to be served with the Bruins. Brandon Carlo established himself as a top-four defenseman last season and David Pastrnak exploded into a game-breaking force in his third NHL season with 34 goals. Then in the playoffs, 19-year-old Charlie McAvoy got a head start on what’s expected to be an exciting upcoming season for him in Boston. There’s more to come this season as draft and development continue to crank at a high level for the Black and Gold. There was ample evidence of that during last week’s B’s Development Camp that wrapped up on Sunday afternoon. MORE BRUINS Sweeney: Bruins looking to get Pastrnak deal done in the
