I think the follow stuff is hindsight really, it's more that they (Trott) plodded along to a total that even the very best Australian side ever in history would never have achieved, let alone this NZ side.
They should have set them 350 max and if they had they would have had them out by now. That's the issue, I think the follow on is irrelevant myself.
I'm going back on what I said about Compton mind, I reckon Root could open and Bairstow play middle order with KP when he returns. Compton ain't good enough.
