Whether he's second or third best in the squad is beside the point really, our OD quick bowling depth is atrocious. I'd back our first choice bowlers to do well pretty much anywhere but beyond that there is absolutely nothing. A line up of Patel/Bresnan, Broad, Swann, Finn, Anderson is pretty damn good, but then look at the rest of our options. The main reason we've done well recently is because we've kept a (close enough to) first choice attack in most of our last few series.
Edit: Or have at least got away with one or two passengers in the bowling, usually Jade.
