It happened so often this season — sometimes Ty Lawson would play aggressively, and other times aggressive defense swallowed him up. Moving forward, what can Denver's point guard do to be more effective more often? "I probably never feel that Ty is aggressive enough," Nuggets coach George Karl said. "I'd like to see Ty drive the ball in the paint 30-40 times a game." For Karl, a key to Lawson's game is rebounding. It sounds weird, considering that Lawson is listed at 5-foot-11 and primarily plays on the perimeter.
