If one really thinks Pache is a FV 60 guy, then that offer is outrageous.
I think Pache is being a little over hyped due to the success of guys lke Albies and Acuna biasing folks a bit, and don't agree with his FV 60 rating. Even if one values Pache as more of a high 50 or 55, then adding Gohara (himself a high 50 or 55) is still way too much value for Realmuto (Allard is essentially filler).
A fair package for Realmuto (~$60M in surplus value) is a single FV 55 guy as the centerpiece, a high 45 or 50 as the other valuable piece, and then 1-2 filler pieces. If someone truly views Pache as a FV 60 guy worth $60M by himself, he is completely off the table in discussions for Realmuto unless it's a 1 for 1.
Would I do Pache for Realmuto straight up? Not if I can sign Ramos or Grandal at good value, but I would probably make that swap if the bidding for those 2 FAs went crazy.
