If the Jaguars want to get troubled receiver Justin Blackmon’s attention about straightening his life out, maybe they should show him a picture of the man identified on the Mississippi Department of Corrections docket as inmate #156017.

The mug shot next to it belongs to none other than former Jaguars’ five-time Pro Bowl receiver Jimmy Smith, who is now serving a six-year prison sentence for possession of a firearm by a felon and possession of cocaine.

Like Blackmon, who was convicted last year of aggravated DUI and will miss the first four games of the 2013 season for violating the NFL’s substance abuse policy, Smith faced nearly identical hurdles during his career that threatened to end it prematurely. The former Jaguar was arrested for drunk driving in 2001, then missed the first four games of the 2003 season for violation of the league’s substance abuse policy.

Now Smith has added the darkest chapter to a life plagued by various demons: the prospect of sitting in jail until November, 2018.

I’m not suggesting Blackmon is heading down the same path, but their off-field issues are eerily similar. Smith remained in denial for years about demons that undermined his career, and obviously continued after football. Twice now in the past year, Blackmon has denied having any problems with drinking or substance abuse.

We don’t know for certain what Blackmon did to merit that four-game suspension, just as it remained confidential a decade ago about why Smith had to sit out the first four games of that season. By the way, the Jaguars went 0-4 and never recovered in 2003, finishing 5-11 in coach Jack Del Rio’s first year.
