The main difference between the teams is the quality of bowling. Pakistan’s batting averaged 248 per innings without Babar, so if we sub Babar in for Haris Sohail, who averaged 7 per innings, and we assume Babar has a decent series averaging 40 (even though he averaged 48.75 in England and that was considered a relative failure) that becomes 241+40 or 281 per innings by Pakistani batsmen.
Next, let’s factor in Jamieson. He accounted for 16 out of 40 wickets taken by NZ at an average of 11.68.
Let’s say that all 16 of those wickets would have otherwise been taken by Boult, Southee, and Wagner (for the sake of comparison, let’s assume he’s fully fit, rather than using Matt Henry who averages 93).
Together, Boult, Southee, and Wagner have 20 wickets between them at an average of 30.57. That’s shockingly average! I’m not even factoring in the fact that Boult and Southee would not have access to the new ball, or that 6 of these 20 wickets are from Pakistan’s last 5 batsmen (the tail).
Therefore, let’s assume that this average of 30.57 holds consistent, even though a more refined statistical model (which I’m not good enough to compute) would probably increase this average to 35 or more if Jamieson wasn’t in the attack.
Together, 30.57 accounts for a difference of 18.89 with Jamieson’s 11.68 average. That’s 18.89 more runs conceded per wicket, for 16 wickets over 4 innings. Per innings, that’s 4 wickets, which means 18.89*4 = 75.59.
So in addition to the 281, if we add in another 75 runs, we would have mustered an average of 356 per innings with Babar and without Jamieson, instead of 248 per innings (the current average). This is assuming Babar has a mediocre/below par series, and also assuming Boult, Southee, Wagner are just as effective with the old ball as the new ball, and also inflating their average with Pakistan’s tail.
That’s very decent. Contrary to what most people think, I do not think our batting was that bad in NZ, it was simply exposed without Babar (if he had been in the side, the main batsman exposed would only have been Shan, with Abid a distant second).
The difference is mainly in our bowling attack. We conceded 604.7 runs for every 10 wickets. I won’t do a statistical dive for with or without Williamson, there’s really no point.
