The HIA system for head knocks has a quick and strict line of questioning attached to it.
Firstly, on the field, secondly, down the tunnel, a set of questions. Any doubt you're out.
The DRS system, around somewhat longer, seems to still have a lot of uncertainty about it. Where a ball pitches, where a ball makes contact and it's forward path after contact continues to provide conjecture. And to be very honest, the Blackcaps have a very poor record of its implementation.
For a start, for me, the DRS system should only apply to batsmen one to eight. Anything after that for nine, 10, 11 is a bonus, so don't go saving it for them.
On the pitch, you’ve got 15 seconds to decide. So the non-striker to the striker, ‘Did you hit the ball?’, striker to non-striker, ‘Where did it hit me? Would it hit the stumps?’.
You've got to simplify it. You've only got 15 seconds. It seems Will Young, a very valuable wicket, is the last victim of getting it wrong. In these vital spinning Tests, it's more important and apparent than ever. The spinners will win this Test. That was a given the day this tour was announced way, way back.
It's so lopsided in their favour it's not funny. Just as it is for the quicks when we host teams here. Unfortunately though for us, that is now coming to our detriment in the subcontinent, and we'll always do so unless we learn to play it better.
It's a hell of a compliment to Tim Southee and Kyle Jamieson that we're actually still playing this Test match. Our three spinners bowled 102 overs. For India, 10 out of the 11 scalps they've got so far are to spin. They opened the bowling with two spinners in the second innings.
The greatest of the tweakers, Shane Warne, marvelled at our success in winning the World Test Championship final but without having using a spinner. He did say it was somewhat disappointing and a poor reflection. He's a tad bias to spin, we know that, but we need to shift ours a little bit more in that direction.
We have to learn to bowl it better, and when we do, we'll learn how to play it better. It might be time to invest in some full-time overseas coaching or maybe discover a Devon Conway type who can turn it square.
Surviving today is temporarily sealing the cracks. We have to get more revolutions on the ball and stop hiding in the grass.
