While the 28-year-old has proven to be a star pass rusher on the football field -- he was a 2011 first-round pick who recorded 44 sacks in 50 games with the San Francisco 49ers -- his once-promising career has been derailed by a heap of off-the-field issues -- including instances of substance abuse, a hit-and-run, domestic violence and possession of illegal assault weapons.
Smith hasn't played a snap since 2015 and is currently banned from the NFL due to his status as a repeat offender of the league's substance abuse program.
