Justin Kubatko: Scottie Barnes last night: 31 PTS 17 REB 6 AST 14-21 FG Barnes is just the seventh player in NBA history to record at least 30p/15r/5a in a game before his 21st birthday. He’s the first rookie to reach those marks in a game since Blake Griffin on March 23, 2011. pic.twitter.com/sudgKCGe1X
