I absolutely love that idea.
Duran ($49.5mill) and Abreu ($26.2) give a surplus value of $75.7mill to SD. This is just shy of Tatis ($83.2mill)
Adding in a single player like Mikey Romero (8.3), Jhostnyxon Garcia (7.8), or Kyle Harrison (9.4) makes it a fair trade package on that metric. I imagine they prefer Harrison. Young, cheap pitching is like a trump card in these deals…
