Deron Williams has looked like a different player since the All-Star break, and says he has a secret weapon that has helped make it happen. “Secret stuff,” he said with a smile before Tuesday’s Nets practice. “Double secret stuff. “I’m working with an osteopath. He’s been manipulating my bones, moving stuff around.” It’s only been three games, but Williams has been superb, averaging 23.0 points and 6.7 assists while shooting nearly 50 percent from the field. It’s a similar jump, at least so far, to the one he had after the All-Star break a year ago. Williams said he’s feeling as good as he did the second half of last season. “It’s rhythm,” Williams said, when asked if health or rhythm was more influential in his recent turnaround. “I’ve been working with this guy who has been helping me out, doing some stuff with my ankles. It’s a combination of those things.” Williams even looked like he tried to go up for a dunk during Sunday’s win over the Lakers, which he finished with 30 points, seven assists, five rebounds and a career-high six steals, and admitted he was going to try to before getting fouled on the play.
