Gentlemen, please....
On the luck thing, some players are "lucky" players, or at least look that way. Mark Taylor used to look a bit lucky, coz he'd play and miss a fair bit. But then, I heard it said that he was "good" at playing and missing, because he tended to play the first line of hte ball, and not adjust his stroke towards it as it moved.
On Vaughan, I thought when he came out here last Ashes tour that he was the best English batsman I'd seen since Gower, maybe since Boycott. Technically he is very correct, save for when he's out of form his feet don't move and he loses his off stump a fair bit. But when he's in form, he's a really good player to watch - his cover drive is a thing of beauty, and he can play off both feet. Well done him.
