Right, I didn't mean to imply they'd be rebuilding. There's still a lot of talent, but Armstrong is on the record as saying they are going into year 3 of a 5-year window to win the Cup. Sacrificing either player means you will realistically lose at least one of those years if not two. Trade Parayko, and you get nothing back but futures since you can't take on salary. Nice, but doesn't help now, or maybe even next year. Not resign Pietrangelo, and you get worse, but at least you have some cap flexibility to try and keep that window open a bit.
