EL SEGUNDO, Calif. -- Shaquille O'Neal is said to have shed up to 20 pounds. Brian Shaw lost 15 pounds no one asked him to lose. Kobe Bryant cropped his hair close to the scalp and made his biceps swell significantly. Rick Fox took up tennis and did something basketball-related every day of the summer but four, by his count. Derek Fisher worked out all summer because, for the first time in three summers, he wasn't coming off foot surgery and could actually stand upright.
