I think it does a couple things for cheap
1. You just made teams who may be looking into Thor more desperate, by taking out the second best option, and you could probably get back 75-80% of what you gave up for Stroman in the offseason.
2. You could do a lot worse than going into 2020 with DeGrom, Syndergaard, Stroman, Alonso, Nimmo, Conforto, McNeil.
