Talent is immense, no doubt about it but if you're not incentivizing the strike rates in T-20 then you deserve to doom. You should never expect becoming impact player in T-20 if your SR is below 140, period!!
You are missing one critical point which is the bowling factor. Scoring at lower strike-rates is absolutely fine as long as they don't waste too many balls. On the other hand, bowlers need to focus on improving their economy rates and taking wickets more consistently.
Probably no one expected such disaster of South Africa batting lineup. I was thinking that South Africa will easily win this series, but now I have doubts about it.
Wrong. These ups and downs are pretty common in the T-20 format(Especially the IPL). Never underestimate any team in the T-20 format which is drastically different when compared to the ODI and Test formats.
In today's match, India scored only 56 runs in the first 10 overs. The run rate was less than 6. They should have collected at least 70 runs in the first 10 overs.
So? The final result is all that matters at the end of the day. India convincingly destroyed SA in recent matches which is the crucial point.
