Watching these playoffs makes it all the more obvious that we didn't get enough for Hader. Its hard to believe that teams like Toronto, Seattle, and the LAD were not interested in Hader and wouldn't trade more than a probable 5th outfielder, backend starter and awful veteran reliever with an expiring contract for the best reliever in baseball.
As for Lamet it was all financial as the Brewers didn't want to pay his contract so the DFA was all about saving money.
