Part of the joy of being a Celtics fan this year is having Kevin Garnett on the team. I'd known about him peripherally in the past, but I paid more attention this year. He's such a likeable superstar because he cares so much.
I found this interview from a couple of years ago, when he was with Minnesota and things weren't going well. It's remarkable:
Seriously, I'm not sure I've ever seen something quite like this.
When he says he doesn't like losing, he's not kidding. When he says it's not about him, it's about his team, he's not kidding.
