Chris Bosh scored 24 points and Dwyane Wade added 22 to power the unbeaten Miami Heat over Charlotte 129-90, the Heat producing the biggest single-game point total in the season's first week. LeBron James, who proposed to girlfriend Savannah Brinson the night before, finished with 16 points, nine rebounds and five assists for the Heat, which lost to Dallas in last year's NBA Finals. Mario Chalmers and rookie Norris Cole each added 16 points for Miami, which matched Oklahoma City for the NBA's best record this season at 5-0, the best start to a season in Heat franchise history. Miami surged ahead 33-15 after the first quarter, matched the third-largest blowout victory in Heat history and inflicted the second-most lopsided defeat in Bobcats history. Byron Mullens sank two free throws with six seconds remaining to avoid making it the worst loss in the team's history. "That was a high school team in a professional game," Bobcats forward Corey Maggette said of his squad after a 0-for-6 shooting performance. D.J. White led Charlotte with 21 points. Bosh added 10 rebounds and Cole had nine assists for the Heat.
