I think part of the issue with the narrative here is that people either want to take the 'Baz is God' stance or the 'Baz is Al Capone' angle.
Where I stand, maybe comes across that I think Baz is God. But I accept his approach has shortcomings. I was very pissed off at Lord's in 2015, when his gung-ho approach probably cost us the Test, for example. And there's going to be times where England **** their pants trying to play the approach they're trying to now. If Stokes had been bowled legitimately at Lord's, that narrative becomes potentially very different. New England skipper slogs out to a part-timer on 1, and loses Test won't go down well in the red tops. It didn't, but to use a tired old phrase they'll live and die by the sword.
But to me, I feel like Baz is good for that side now. And they'll swing way too far the other way from the scared little kitty cats they were in the Ashes, to a group that tries to push the envelope too much at times. Maybe that will lead to them finding where the middle point is, where that balance of daring and discipline meet.
And yeah obviously, sorting out the technical difficulties faced by their top order apart from Root is a massive part of that as well, that won't be remedied by Brendon McCullum. And they'll need to deal with sub-continent conditions, pace + bounce in Australia which won't come from 'positive intent'
