I very much like the trade for the Pens - who cares about futures honestly. They have Crosby, Malkin, Letang and Karlsson. I expect them to make the playoffs as a low seed (baring major injuries) and then you never know. Will they win a Cup? Probably not ... but what is your alternative scenario? There is pretty much not even an alternate scenario. You have to run out Crosby's and Malkin's careers and until that you can't even start preparing any rebuilds. You might as well load it up as much as you can.
The upcoming rebuild will come and it will be a rough one but that is fine. Think Detroit from the Datsyuk, Lidström, Zetterberg and Co. days up until... well up until now pretty much. It's still the same rebuild.
