About the only positive from this trade is the Rangers replenishing some of their draft pick pool after trading away so many picks in recent years. These picks likely won't do anything for them in the next few years, but it's always good to keep filling up the draft pick pool, if you're going to have high end contracts, you need cheap ELCs (hopefully fully developed or at least developing) to fill out the roster. Yes the cap is going up, but it's good to have flexibility.
The Rangers bleeped up Kakko's development, though I'm not absolving him of any blame. He starred at the World Hockey Championships in his draft year, but it went all downhill from there. I had been a supporter of his and I wish him well with the Seattle Kraken.
I've barely even heard of Will Borgen, so I'll reserve judgement for now.
