Peyton Manning was labeled "the guy who can't win the big game" for years. He won a championship, and the vultures backed off. LeBron James was dogged the same way and, rather conveniently, the haters are a lot quieter now. For whatever reason, winning a championship is the mark of a truly great player, except tons of schmos have rings, while Charles Barkley, Reggie Miller, and Patrick Ewing combine for zero. LeBron James would be getting killed right now if Ray Allen didn't drill a clutch three-pointer in Game 6. He'd be just as great a player if that ball had rattled out.
