As a coach, one thing that used to frustrate me was one player would make a bad decision, and that's all you would read about in the papers all over the country. We have so many athletes do so many wonderful things for other people, and you never read about it.
I'd say handling people is the most important thing you can do as a coach. I've found every time I've gotten into trouble with a player, it's because I wasn't talking to him enough.
