The Wynn Las Vegas filed suit in Nevada against Sixers legend Charles Barkley alleging the Round Mound of Rebound never paid back $400,000 in markers the casino spotted him in October, TMZ reported earlier today. The Associated Press is reporting that Barkley, reached on an Alabama golf course, says the unpaid debts are "My mistake. I'm not broke, and I'm going to take care of it." If only all lawsuits were settled so quickly. Barkley, you may recall, revealed in 2006 that he had a gambling problem and estimated his lifetime losses as $10 million.
