It was obvious he was high as all get out in the video. Just because the cops didn't find drugs when they arrived doesn't mean that drugs were not consumed before hand. This was not 'normal' behavior. People don't just do stuff like that without drugs being involved.
His brothers keeper??? Why was he partying at some down trodden apartment complex with his brother in the first place? His brother doesn't sound like much of a savior to me, sounds like they were up to no good and his brother was clearly involved in some way.
It's a shame, for once I wish these young men would appreciate the opportunity in front of them, there are much better ways for Zay to be spending his off season for himself and for his team!
