The squad has been made, and we can't change any of that now. However, it leads me to wonder if there are aspects of the game that we are forgetting, areas where we are not directing enough attention. You see, South Africa is likely to enter the first test match with the following combination:
Dean Elgar (LHB)
Aiden Markram (RHB)
Rassie Van Der Dussen (RHB)
Faf du Plessis (RHB)
Quinton de Kock (LHB)
Temba Bavuma (RHB)
Wiaan Mulder (RHB)
Keshav Maharaj (RHB)
Tabraiz Shamsi (RHB)
Kagiso Rabada (LHB)
Anrich Nortje (RHB)/Lungi Ngidi (RHB)
They will most likely go in with this XI for two reasons: they have only two recognized spinners and secondly, they won't make their tail too long.
Looking at the batting styles (LHB or RHB), I can already see that Yasir Shah will be a guaranteed starter because he can take it away from all the right handers. However, there is a chance that he won't play if we instead opt for Nauman Ali. The emphasis made by a lot of people, including me, about the inclusion of Sajid Khan might not make too much sense considering how many batsmen are right handed. If the management thinks like that, they would be thinking down the wrong track. Yasir and Sajid are a must because spinning the ball both ways is very valuable.
In Karachi, our bowling attack should be composed of Shaheen Shah Afridi, Hasan Ali, Yasir Shah, and Sajid Khan.
Now our batting.
Rabada averages 22.15 vs RHB and 19.43 vs LHB.
Anrich Nortje averages 21.36 vs RHB and 31.81 vs LHB.
Ngidi averages 15.07 vs RHB and 32.87 vs LHB.
Keshav Maharaj averages 26.33 vs RHB and 23.21 vs LHB. However, Maharaj has taken 51 wickets against positions 7, 8, 9, 10, and 11 alone, meaning that he's not that threatening.
What you'll notice is that in some cases, there is quite a large deviation between the bowling averages of South African bowlers when determining batting style.
Therefore, I'd walk into the Karachi test with:
Imran Butt
Abid Ali
Azhar Ali
Babar Azam (c)
Fawad Alam
Saud Shakeel
Mohammad Rizwan
Yasir Shah
Sajid Khan
Hasan Ali
Shaheen Shah Afridi
That should give us enough bowling and enough batting to post large totals.
