The AP reports: Dwyane Wade still believes his knee will be ready for the Beijing Olympics. The Miami Heat guard, who missed the final 21 games of last season because of chronic soreness in his surgically repaired left knee, said Sunday that he’s been playing 5-on-5 games for about a week with “no problems.” Wade is spending much of his offseason rehabilitating in Chicago, with eyes on both getting a spot on the Beijing-bound team—USA Basketball will finalize its Olympic roster later this month—and ensuring that he’s fully healthy when the Heat open training camp in late September.
