DALLAS — When asked today if he had ever stayed late after a game to work on his shooting, Pau Gasol said with a straight face, “Usually, I’m hungry after a game.” Kobe Bryant shot baskets for almost 90 minutes after the Lakers’ loss Thursday night to the Miami Heat, finishing a little after midnight local time. Bryant said it wasn’t the first time he had gone to a court to shoot, but it’s usually one near his home in Orange County.
