Smith earning more than league-minimum after missing the past four seasons is eyebrow-raising.
The 30-year-old hasn't appeared in a game since 2015, when he played for the then-Oakland Raiders, due to a series of off-field issues.
The Cowboys are no strangers to giving players a second chance.
Cowboys owner Jerry Jones has a history of trying to resurrect the careers of troubled defensive players, with mixed results. Smith is still awaiting full reinstatement from the NFL, but the process is underway, according to NFL Network's Mike Garafolo.
Smith was an instant difference-maker in San Francisco, racking up 14 sacks in his rookie year.
The problems began in 2013, as Smith was arrested on suspicion of driving under the influence and possession of marijuana after a single-car accident in San Jose, Calif.
Smith was as good as any pass-rusher in the league at the beginning of his career after being selected seventh overall by the 49ers in the 2011 NFL Draft.
It continued into 2014, as Smith pleaded no contest to six separate charges incurred and was sentenced to 12 days in jail.
Oakland retained Smith's contractual rights before releasing him in 2018 after San Francisco police issued a warrant for his arrest in a domestic violence case.
The following season, Smith was even better, rattling off 66 tackles, 19.5 sacks, an interception, and three forced fumbles en route to a Pro Bowl appearance and a First-Team All-Pro selection.
We have no idea what Smith's skill level and football shape is at this point, but NFL teams are desperate for pass-rushers.
The following season, Smith served a nine-game suspension for violating the NFL's substance abuse and personal conduct policies for the incident that occurred the year prior.
Still, recent reports indicate that Smith is clean and sober.
Fox Sports' Jay Glazer first reported the deal, which Smith later confirmed via Instagram.
