TrueHoop really is the best basketball resource on the web. Regarding Mardy Collins:
"That's just the way I was brought up, with Coach Chaney, we don't just
give guys layups. It's anybody in basketball, it's not like I'm trying
to intentionally hurt a guy. That's just something I did growing up. In
Philadelphia, that's how we play."
