On its day, our attack is up there with the best
On their off-days, it's among the worst
They never really seem to bother with the middle bit
In terms of what it's capable of, I think our attack can be one of the best but they need to go and get some more consistency. Broad is only young and is getting there, Onions is fairly inexperienced too. Anderson is a lot better than he was, still must only be about 27/28 and coming into his own. Swanneh is about 30/31, and he's had about two bad Tests in his whole career, what a champ
In other words, give it two years and it'll be the undisputed best attack in the world
