Kobe Bryant, ever the optimist, still thinks the Lakers can win a championship. "It doesn't matter what anybody else is saying. That's the goal that we have," he said Saturday. Bryant, though, wouldn't be healthy enough to take part in the Lakers' first practice of training camp, talking to reporters and eventually ducking back inside the underbelly of the team's El Segundo facility. He is still recovering from a torn Achilles' tendon and has started running on a special "anti-gravity" treadmill that allows him to essentially decrease his weight with an air-pressure chamber that envelops his lower body and reduces his running impact.
