Disagree totally. Kane played a matchwinning innings chasing a 170-ish score. A combined 4 (20) from #4, #5, #6, #7 and #8 lost it for NZ.
OK will agree to disagree his SR was 116 after facing 60 balls. We needed an overall SR of 143 over the whole inning.
It was only Munro's fireworks that gave us a sniff.
T20 batting strategy is in its infancy. Things that will be different 10 years from now:
1) there will be no anchormen in any team. Each guy will have to be capable of scoring at a SR of 140 plus without it raising an eyebrow.
2) each new batsman will take two sighters to get his eye in instead of two overs.
3) Scores of 200 plus will be common place.
Kane's inning belonged to the T20 tactics of 2010. Now granted he didn't intend to bat that slowly. I have seen him open for ND in the HRV cup and he made 50 off 38 balls. The only problem I had with that HRV cup innng is that he didn't generally hit the ball in the air and somehow batted quickly just by finding the gaps that isn't a sustainable approach against the world's best bowlers or at least you can't maintain a strike rate that healthy without some risks.
He needs to change his approach in the next match and be prepared to slog from the second over. It grinds my gears when we try to work a spinner for singles when there are only two men outside the circle in a T20.
Again in his defence they had studied him and brought the field in close so that he couldn't just drop and run.
He didn't single handedly cost us the game as you are correct that the middle order was woeful, but Colin Munro was the only person who scared them.
