Bulls forward Drew Gooden says that he's delivered on his promise to expand his game this summer.

"It turned out excellent," Gooden said. "I actually kind of surprised myself. I was capable of doing things I never really worked on in the off-season. I wanted to expand my game this summer and I think I did that. I worked on my outside shot more than anything."

Gooden spent about four weeks this summer in Vancouver working with personal trainer Alex McKechnie in hopes of solving the problem.

"I felt my lower abdominal region wasn't strong enough to fulfill a whole NBA season," he said. "That's why I had to shut it down at the end of last year. That's completely behind me now."
