LeBron James was whistled for traveling, ending a possession that could have given the Los Angeles Lakers a fourth-quarter lead. A couple minutes later, he did it again. In the time of the game when he usually turns it up, James turned it over Sunday night, part of a sloppy performance by the Lakers in a 115-104 loss to the Miami Heat in Game 3 of the NBA Finals. Knocked off track early by Anthony Davis’ foul trouble, the Lakers wasted a chance to take a 3-0 lead, which has never been blown in NBA playoff history.
