I agree with this totally, but also think that his accuracy is only half of his problem. He doesn't seem to know how to "outthink" a batsman; this is where the likes of McGrath excelled throughout his career. Broad seems to bowl individual deliveries, rather than spells. Yes, he has a lot of variations, but they don't apper to lead anywhere. He won't try to keep it tight for a couple of overs with quick, length deliveries, then throw in a slower half-volley, for example. He will try a few quick length balls, then get bored and try a few cutters. It is this, rather than accuracy, that is his main issue, and until he can correct it, he will never be a top bowler, no matter how accurate he is.
