The Matt Harvey trade tree is actually a very sad tale:
Late 2013: Harvey for Wieters (Harvey goes down for TJS a few months later and Wieters has played 26 games since the start of 2014)
Offseason 2013: Harvey for Braun (after putting up a career 148 wRC+ through his age-29 season, Braun has been in and out of the lineup since with a 108 wRC+ in 645 PA)
Offseason 2014: Braun for Wainwright (Wainwright tears his Achilles tendon 4 starts into the season)
Boxy leaves all of this mayhem with a mid-prime ace.
