It's not his ankle. It's 4 years of rehab every off season. He had doubts if he'd play again last year. Then an injury he can't figure out. From what he said I'm guessing he battled deep depression previously stemming from injury and found himself in the same dark place. His body breaking down led to his mind doing the same. It's incredibly sad. The same reasons we all saw the highs when he played are what likely led to the lows we didn't. Passion.
He's an incredibly smart, unique, gifted human being. I just hope he finds a way to get the same happiness back that made us all love him.
