Before the NFL Scouting Combine, University of Florida star Percy Harvin should have gotten drunk out of his gourd, puked on his shoes and passed out behind the wheel of his car.

If only he had done that instead of hypothetically smoking a marijuana joint and perhaps laughing uncontrollably at “The Three Stooges Meet Hercules,” then maybe Pro Football Weekly would not be calling Harvin the biggest risk in the upcoming NFL Draft.

Sadly, this is the confounding, contradictory world we live in — a world where Harvin would be more appealing to NFL teams if he’d been arrested for a police-confirmed DUI than he is now because of an unproven Internet report that he tested positive for marijuana at the Combine.

The unconfirmed report, printed by NFLDraftBible.com, set the wheels in motion for Harvin to be labeled a monumental character risk by Pro Football Weekly. Meanwhile, the ruling hypocrisy of sports continues to promote and glamorize the use of a much more dangerous and prevalent controlled substance — alcohol — through its lucrative beer sponsorships on TV and beer sales inside stadiums and arenas.

The legality of the two substances notwithstanding, nobody can deny that alcohol causes much more pain and suffering in sports than marijuana. Case in point: The two recent and fatal sports-related accidents tied to drinking and driving

Last week, promising young California Angels pitcher Nick Adenhart was among three people killed after an alleged drunk driver with a blood-alcohol content three times the legal limit blew through a red light and broadsided the car Adenhart was riding in.

Last month, Cleveland Browns wide receiver Donte Stallworth hit and killed a pedestrian who was crossing a causeway in South Florida. Blood tests revealed Stallworth had a blood-alcohol level above the legal limit, and he was charged with DUI manslaughter.

No, I’m not here today to give Harvin a free pass if he smoked pot. If indeed the reports are true he tested positive for marijuana, I’d be wary about drafting him. Not because of the evils of reefer madness, but because any player dumb enough to smoke weed when he knows he’s going to be drug-tested probably isn’t very committed to his profession.

Still, it’s hard to ignore the massive double standard in sports between alcohol and marijuana. Look no farther than Olympic swimmer Michael Phelps, whose sport suspended him and a major sponsor abandoned him when a photograph surfaced recently showing Phelps using a marijuana bong. Contrast that mammoth controversy to five years ago when Phelps was arrested for drunken driving and was allowed to continue swimming and didn’t lose a single endorsement.

Now ask yourself: What’s worse — taking a bong hit at a college party or getting snockered and putting yourself and others at risk by climbing behind the wheel of your Hummer?

Why are professional athletes repeatedly suspended and fined for smoking pot, but not so much for abusing alcohol? Why do most pro sports leagues have black-and-white policies and punishments for marijuana use, but a gray area when it comes to DUI or other alcohol-related crimes?

You can go 10 drinks over the legal limit and you’re fine, but if you go one toke over the line, you suddenly become a character risk.
