You don't punish someone extra because they have a disease.
You do punish people if you think it will do them some good or discourage others from doing bad.
Joe's point is that sometimes you have to send a strong message to certain people to get through to them and force them to become serious about changing their life. That's fair, IMO, but we're in no position to judge whether that's the best course of action for Delonte ... and that's the bottom line.
Is taking Delonte away from basketball going to help him?
I don't think so. His problem didn't occur on a basketball court, it happened during the off season.
There's a lot of things that could potentially be done to help Delonte and prevent a re-occurrence, but they have to be evaluated by the parties involved.
