No to Alonso. Yes to Bellinger and Soto.Cubs are now rumored to be in on Juan Soto. Don't get me wrong, Alonso and Soto in a lineup is pretty damn salty, but I'm not sure how I'd feel of giving up your farm for 2 rentals who will most certainly hit free agency because of their agent.
I wouldn't hate the idea of giving up the farm for Soto and then calling the Guardians for Ramirez/Bieber and sending the farm in that situation.
But getting involved in the Soto rumors tells me Bellinger is probably a goner
