I could easily argue that the money we used for Porcello was money that we saved from letting Lester go, so we should really be comparing Lester and Porcello.
Then there are the bad contracts for Pablo, Castillo, and to a lesser extent Hanley, which add up to the same 265 million that we saved on the Dodgers trade.
The problem with advocating the greatness of this trade is that you can't analyze the benefits of it in any logical fashion. You have to 'follow the money', but the money went in many directions, some good and some bad.
