Enscheff can correct me if I'm off on this, but I see Perez's trade value breaking down like this. I'd project him for about 6-8 WAR over the next 3 seasons. Probably closer to 6. Something like 2.5, 2.0, 2.0. That is about 58.5 million in value if you go by the 1 WAR = 9 million model. He is owed 36 million in contract obligations over those 3 years so you are left with 22.5 million in surplus value. That in and of itself is pretty darn cheap and wouldn't cost us much in terms of prospects. But I do think there are some roadblocks. Firstly, he is one of the Royals best trade assets so they'd want maximum value. He also has a high value reputation around the league, being an all star 6 seasons in a row. So I think the Royals would over-value him significantly over the 22.5 million in actual surplus value that he is worth.
If I had to guess, the Royals would probably be willing to eat a little bit of his contract, but they are going to want an significant overpay to move him. I would say something in the 40-50 million dollar range. I think maybe something like Bryse Wilson, Luiz Gohara, and Alex Jackson could maybe get pretty close to getting the deal done. I think that is a significant overpay, but I'd imagine that most people on the board would be okay with that price for Salvy. Not sure what I would think about it. It'd be a weird situation in my opinion.
