Maybe Johnny Manziel simply doesn't give a damn about his reputation.

The troubled NFL quarterback was photographed over the weekend partying with Scott Disick at 1Oak in Las Vegas. Not a good look at all, considering that Manziel reportedly has a serious alcohol problem and Disick has been known for his various substance-abuse issues as well. 

Making matters sadder is this hang-out session seemed premeditated, judging from the fellas' nearly identical outfits, as posted onto Disick's Instagram account.

After hanging with Disick, Manziel reportedly hung out with former Cleveland Browns teammate Josh Gordon, who also hasn't been a stranger to substance abuse.

Don't forget that this comes a week after Manziel was seen taking Champagne bottles to the head in a Miami nightclub following learning that the investigation into his alleged assault of his girlfriend was being sent to a grand jury.

His father, Paul Manziel, also already told the Dallas Morning News that his son twice refused to enter rehab and if he doesn't get help "he won't live to see his 24th birthday."

Part of that rehab should be laying all the way low and out of nightclubs and the night life, period. 

Also, the company Manziel is keeping right now isn't helping his damaged reputation.

At this rate, Manziel may never get an opportunity to play in the NFL again. But does he even care?

You can't begin to tell Johnny Football about the NFL, when he hasn't sought enough help to get himself all the way clean. 

This has nothing to do with football, anymore. It's more about a young guy getting help and saving his life, before it's too late.
