I hope you're right. He's a Brown, and like any Browns player I want him to succeed.
But if alcohol is a problem for him, and he is trying to "control it", well then he's fucked. If a person has a substance abuse problem, they can't fuck with that substance. Period. Google Audrey Kishline for a good example of what happens to alcoholics who try to play the moderation game. Sooner or later it's going to bite them in the ass.
(It is important to point out that, as far as I know, we were never told what his real issue was in going to rehab. I think most of us assume it was for alcohol, but it could be anything for all we know. Maybe he's just a coke fiend who drinks like Oliver Reed when he gets jacked but when not snorting yak he can have a couple beers and be fine etc etc etc. Maybe he has a heroin problem. Who knows. Anything is possible.)
Bottom line: Alcoholics shouldn't drink. If they do, bad shit happens. AGAIN, I DON'T KNOW IF JM IS AN ALCOHOLIC, but if he is and he is still drinking, then sooner or later this is gonna happen:
