Rask posted on my thanks tag: "superstar coming back. It would almost certainly be Abreu, Giollito, and I would guess 3-7 additional minor leaguers."
Rask, you are so far off base on that.
1) Machado has a single year, and then a Free Agent. His value is less.
2) Even if an extension was allowed, which a window for negotiation for the trade is not, he'd bring in roughly what Stanton did considering the White Sox would be paying the entire contract and not the 80% that the Yankees are paying.
3) The Orioles have already said they want pitching and near ready pitching. The White Sox did not offer Giolito nor Kopech and had the best offer by reports. I am guessing it was something like Fulmer and Hansen/Cease and perhaps a lower quality pitcher like Adams.
