Charlie Villanueva felt like the weight of the world was on the Detroit Pistons as they flew into Charlotte, N.C., for Saturday night's game. A 10-game losing streak will do that to an NBA team. Villanueva made sure the Pistons could breathe a sigh of relief Saturday night, scoring 14 of his 18 points in the fourth quarter -- including a go-ahead driving layup with 15 seconds left -- to help Detroit defeat the Charlotte Bobcats 92-91 to avoid matching its longest losing streak in three years.
