Ghostguy said he isnt an alcoholic. Stop pretending he is.
Whether or not Manziel is an alcoholic can and might differ from whether that's the base "narrative" that will be in play by himself, his agent, his PR and his other handlers.
A lot of people years ago were a bit baffled when Sheriff Roger didn't completely hose down Aldon Smith the first time he had a public and messy alcohol issue. Well, alcohol is closely aligned profit wise with the NFL. Look at the beer commercials, look at alcohol sales during games, look at sports bars, even look at the college level where the "alumni" section is just a cordoned off heavy drinking area for people who give big money to their old universities.
When it comes to alcohol specifically, the NFL will and does tread very carefully. There is no PR spin control that can disassociate big business with alcohol from the NFL and the football culture in general. Kind of a tough way to deal with an issue when your stadiums are pumping out beer by the truckload, booze banners and sponsors are everywhere, fans are cheering at sports bars with drinks in their hands, and then Goodell tells some player that he's an alcoholic POS who needs to spend a year away from the league.
Alcoholic or not, the right play to minimize any kind of league backlash, Manziel SHOULD play the alcoholic card. There are also a lot of functional alcoholics and recovering alcoholics in the press corps, which will further generate sympathy for him.
