I used to despise him, but I feel now I see him in a different light. He's legitimately crazy and not at all smart, but I think he has a good heart. The work he's doing toward improving mental health understanding is significant; not just in the money he's put forth toward it (a LOT; over $10 million so far), but the focus he's made toward it is truly a "greater good". I think it more than makes up for his ridiculous antics as a youth in the league.
One of my best friends is a psychiatrist (and Celtics fan) and he talks very highly about all of the good RonRon has done in the past few years.
