The only thing I will say though is that if Djokovic can change, so can Murray. Djokovic has become a big match player after a long time being accused of bottling it when he has to fight against the big boys, but right now he's elevated his game and his mental toughness to a different level and he totally deserved to win this Slam. So yeah, Murray still has everything required to compete at this level, it's just that he has to overcome his own nerves... in my opinion anyway.
