This is part four of a series analyzing Astros trades from 2014-2018. For a review of the methodology and caveats go to Part I here.
This is a review of how the trades turned out, understanding that at the time the trades were made the teams involved used the best information available to maximize the chances of an advantageous transaction. But all trades are based on probabilities, and like any form of gambling, the actual outcomes may not be those desired. So this is not intended as a criticism of the trades at the time they happened, but just a review of how lady luck eventually blessed each trade in the end.
