Tensions between Pistons head coach Larry Brown and Nets president Rod Thorn were on display last night.  Thorn angrily blew by Brown in the hallway as the coach was talking to members of the media before game 3 of the teams? playoff series at the Meadowlands.  The hostility continues after Brown made comments critical of Thorn?s decision to fire Byron Scott as head coach and replace him with Lawrence Frank.  The verbal jabs continue as well.  "Rod's a hothead anyway. I've played golf with him. He throws clubs. He screams and yells," Brown said Friday.
