I gotta agree with you there Props.
Andy's (not Roddick) negative attitude only detracts from his game.
He has some great tools and could probably use 1 more, but until he has a better self-image, winning a slam is a Herculean challenge.
It's curious that you contrast Murray with Roddick.. Both have come up short in a few Grand Slam finals.. However, each reacts to pressure in opposite ways.. With Roddick, the skills are bright but limited while Murray has an array to choose from.. Under pressure, Roddick gets extroverted while the Scot vents his frustrations on himself, his team, etc. From a psychological point of view, Murray's troubles are not unlike Nole's, till last season, when a blip during a game could turn into a landslide.. In the slams, against the top dogs, Murray lacks 'stick-ability', the ability to stay within touching distance of your opponent, when the chips are down, when the opponent is dictating play, when you are not playing your best.. I hope I make sense..

Still, Murray is a very good player and I respect his skills..
