LAS VEGAS — Warriors forward Draymond Green provided one-word answers to reporters' questions Wednesday after a USA Basketball practice at UNLV's Mendenhall Center. Green seemed upset about something — whether it's how he has been portrayed recently, his scheduled court hearing in Michigan over his July 10 arrest after an altercation with a formre Michigan State football player, or something else entirely, he wasn't saying. Green, who faces misdemeanor assault-and-battery charges over the East Lansing incident, will not be present at Thursday's hearing, according to a source with knowledge of the situation. [...] Olympic team coach Mike Krzyzewski has Green's back. [...] I would rather have emotional people who sometimes make small mistakes than to have non-emotional people who are unwilling to put themselves in a position where they will go to an extreme where a mistake might be made.
