Read thru more than a thousand Kessel posts since the trade and this might be the most succinct.
Don't expect a strong backcheck from Kessel because you wont get more than a few times a season. Don't expect him to dig pucks out or win board battles, that is not his game. Don't expect him to hustle on changes, he won't do it. Don't expect sound bites, you won't get them. Don't expect passion on the ice, that is not who he is.
He will come down the wing and snipe, he will take a pass from Crosby or Malkin and snipe, that is what he does, and basically all he does. And that is a good thing.
