Need advice on blockbuster trade - WHIR

[Dundoula]

Hi. I’d greatly appreciate any feedback on a trade I’ve been proposed. I love trades where I am trading up since it frees up room for snagging free agents and right now my saves are hurting a lot. This is a deep 14 team H2H league with very active managers. The league allows for 10 pickups a week so I’ve been doing strategic streaming and will do it even more if this trade goes through. I want to trade Panda since I think his value will never be higher. I'm trading away my 7, 8, 9, and FA picks for a 1 and 12. Am I giving up too much? Or is getting Cano worth it? Thanks for your time.
