I love Pasta but I just think it's far too soon to shoulder him with the responsibility to fix the sad Bruins offense.
He's too young and still has to build up his physical strength. He got beat around a bullied in a few of his final games, particularly against LA.
The *responsible* thing for the Bruins FO is make the necessary but smaller moves to shore up offense for this season (e.g., Stewart as a buy low with some scoring upside and "heaviness"), make bigger moves off season to significantly improve it (e.g., acquire elite scoring like Hall by trading significant assets: some combo of Rask/Eriksson/Lucic/Krug/or Subban), and introduce Pasta next season on the third line RW, to build his confidence and role.
It is surely an indictment of the FO to be so desperate as to expect an 18 year old kid, fresh off the draft podium, to replace Iginla on the top line. Not quite as silly as playing a 4th line energy guy in Cunningham there, but probably more reckless in terms of Pasta's development.
