BOSTON — Entering Thursday night's nationally televised showdown against the Celtics, the Warriors sit atop the Western Conference standings at 11-3. Golden State could be 14-0, however, if not for forward Draymond Green. At least, that's what Green reckons. "Earlier this season, that enthusiasm just wasn't there for me," Green said Thursday afternoon during a speaking engagement at Harvard's John F. Kennedy School of Government. "It was killing me, because I knew — we lost three games, and I can honestly tell you I am the reason we lost those three games. Part of it, honestly, it just wasn't there for me. I had so many things going on." Green is averaging 10.
