I think that if it was substance abuse, that broght him down, then he can regain his talent and speed simply by playing. That doesn't just dissappear. It's always there. He just needs to get on the field. However, if the injuries have slowed him, then I wouldn't do it. Cause you don't always come back from that. Taking a short look won't help. Someone has to commit to a comeback. He's got a short road back, but it will take at least half a season to know if he can play.
