Is there anything the Mets could offer (realistically) for Contreras and Robertson as a package that would satisfy you, if Alvarez and Baty aren't involved? One or the other to them, maybe, but I don't see both.
All in all I'd rather see the headliner be with the Padres, especially with the possibility of spiking the punch by taking Hosmer. Even without Abrams they just have a lot more interesting trade chips.
