This is a good faith effort by OP.
It's conclusions are not spot on.
from Leafs, I get they wanna upgrade and get something now for a guy who is UFA next year. But a pick now at best is available to help with the run in 2 years, not immediately.
The Leafs need RD which is in short supply, and the parallel of this would be DeAngelo for Leafs 1st. Some variant of that makes more sense.
Rangers have logjam at LD, with 4 good prospects in the pipeline, + atm, Skjei, Smith, Staal + Gilmour.
Do not need LD Gard even if he has some lesser extent ability to flip to right side. He may not be a hot mess there, but also, he is not all that and a bag of chips on defense, which is a paramount issue for a D.
NYR not likely to make picks available, would be looking to move up for better picks if they do. If they were to take a player for a pick, the asset would have to be need, part of package for RD Liljigren, which obv Toronto cannot spare.
Think about it.
for this to work for NY,
they acquire Gard who they do not need for a late pick
they have to flip him and expect to get adequately more than the pick to be worth the risk/trouble.
not happenin now or anytime soon
