It's obviously a small sample, but they do seem to have turned all of the received wisdom of test cricket completely on its head with a 'chase anything' mentality that has obviously grown out of the shorter formats.
I suppose, given the rate they score at the pitches aren't even that bad when it comes to the 4th innings. Having players in the form of their lives obviously helps.
Will be interesting to see how they approach batting first when that happens. Are teams going to start to have to think about putting them in as a tactical choice?
Completely remarkable.
