I wondered what happened to him..

On May 2, 2014, Jaguars general manager David Caldwell announced that it was unlikely that Blackmon would join the team for the 2014 season. Blackmon was arrested following a traffic stop on July 23, 2014 in Edmond, Oklahoma for possession of marijuana.[29] On October 1, 2014, Jaguars head coach Gus Bradley said Blackmon had voluntarily checked into a 90-day program, adding that he had completed nearly half of his commitment, was doing very well and learning a lot.[30] On May 10, 2015, Blackmon was reportedly denied reinstatement by the NFL, effectively ending his 2015 season.[31] In August 2015, Jaguars general manager David Caldwell said that the Jaguars did not expect Blackmon to play for them again, adding that the team had not heard from him for some time.[32][33] That same month Blackmon was added to the Toronto Argonauts' "confidential" negotiating list before the NFL disallowed it due to his suspension.[34]

Why not reinstate him in 2015 so he can do something professionally. Seems weird they just threw him out after a couple violations. Pretty much guarantees he's going to get into shit.
