The shocking decision by the Dallas Cowboys to trade Micah Parsons to Green Bay after four dominant seasons as a pass rusher is far from unprecedented.
A very similar trade happened on the eve of the 2018 season when the Oakland Raiders shipped two-time All-Pro and one-time Defensive Player of the Year winner Khalil Mack to Chicago.
Both trades happened after failed contract talks and featured two first-round picks in return, although Dallas also got defensive tackle Kenny Clark from the Packers.
That 2018 trade didn't ultimately work out for either team.
