The guy lasted a few practices in the NFL, nothing more. At the time, his teammates were shocked at his off-the-field behavior and that he would bring a bottle of vodka, pour it into a sports bottle, and drink it after practice. That idea makes me want to vomit, I don't know how it's humanly possible, to be honest.
I heard he was drinking during lifting sessions. He'd tell his teammates, "I gotta go get my goose (Grey Goose) on." He'd go swig some vodka and then walk back into the weight rooms. A lot of athletes suffer from some form of substance abuse, which is amazing considering how well most of them manage to stay in shape.
