Other than DeSclafani, did those other players/arms do anything special that makes you hit your head?
Buehrle wasn't anything special, but he was solid and a reliable innings eater. Josh Johnson was the biggest bust, but if he was healthy he was a top arm. Reyes still was solid with the bat, but defensively was meh.
If that trade didn't happen, you wouldn't have had the 2015 and 2016 postseason.
