LAS VEGAS — That’s what Jeanie Buss, the boss’ daughter, tells her boyfriend, Lakers coach Phil Jackson. At least, that’s what she tells him during exhibition games, when Jackson makes it clear he could care less about wins and losses. “Jeanie tells me always I’m the worst preseason coach in the history of the NBA,” Jackson said before the Lakers tried to avoid a 0-3 start to the exhibition season tonight against Sacramento. “She’s always riding me about that. I tell her the reality is we’re trying to get the players in shape. Maybe the last couple of games you can get it together a little bit before the regular season.”
