I remember reading somewhere that Wyc flipped over the Telfair gun incident. I guess he's now okay with gun play, or did Danny convince him that we really do need all of the shooters we can get?
Seriously, things things aren't cured, and the problems don't get solved. Sometimes, though, they can be managed and people can become better at recognizing when something needs to happen to manage them. Also, as people age, other factors that confound the ability to manage the symptoms (like hormones, impusiveness, etc.) come under better control, allowing better management of the mental health issue.
Equally seriously, isn't Boston a "better place" in the KG/Ray era than it was when Delonte was here the first time?
