PHOENIX — Here’s what Kobe Bryant said after the Lakers played some less-than-inspired defense while losing to the Phoenix Suns in Game 4 of the Western Conference finals tonight: “You know, coming up here, we lost a sense of urgency defensively. I think our concentration was focused on how to attack the zone. And I think it kind of flipped our attention to detail defensively. Our focus was on the other side of the floor, which doesn’t win championships. So we need to get back to ground zero when it comes to that.”
