Actually 3 different formats - Test, ODI & T20 - still it's cricket though. PAK hasn't won much to be honest with their stable selection outside UAE, that too assisted by lots of toss winnings. In fact stability has made the team's average age officially 31 & has resulted 0-3, 0-2, 1-1 in places where that stable XI wasn't suited. Funky selection may be, but playing Nawaz in UAE & then giving 10 overs, to bring back Zulfiqar very next Test is too much stability as well.
This is extremely poor team selection, because when you have 12-13 players picks themselves, you have just about 2/3 spots to work with - and Inzi failed in that measurably. When 80 marks are given for attendance, you have very little to do in the exam you know. Besides, no one is questioning the batting selections - may be apart from YK; this is whats best available. And selection of Nawaz as Spin "All-rounder" ............ at least give me a respite here.
Now, coming back to your 100's of example - that actually exposes your understanding of the playing condition. PAK's "Stable" team is perfect for UAE, where you can bowl 130 overs by 2 spinners, another 20 by 3rd spinner/part-timer & may be 50 with 2 pacers. Those 2 spinners will give you tight spells, even if they don't get wickets. IN AUS/NZ, it'll be foolish to expect the same with 2 spinners - even for that the initial option was wrong - for the sake of saying, even if I take that PAK can play 2 spinners at MCG & SCG - a 2nd specialist spinner should have been picked. This team was selected after the Adelaide Test, where AUS played 7 lefties & most of them will play against PAK - 2 spinners can be an option, but that's only with Yasir & Ajmal; or Yasir with another Leggi, OR even Yasir with Asghar - NO WAY, Yasir & Nawaz. 0 for this one - still stuck at 80 for attendance. And, you carefully avoided the part - why Asghar was summoned, despite having a SLAO spinner with the squad already, but we can ignore that - the squad is poor, poor not only for that one.
2nd - At Old Traford, Birmingham & finally at Hamilton, it was clearly evident that PAK pacers can't take more than 20 overs work load in an innings, 35 max in a match. For PAK's fortune, the Hamilton Test was rain interrupted, hence, bowlers were never forced to bowl 90 overs in a day - which they had to do in the previous 2 Tests I mentioned & poor Yasir had to bowl 130+ overs on unresponsive wickets in 8 days - Stability didn't help him or PAK much there. Coming to the combination, this squad doesn't have the option of 5-1-2-3 formation for it's picks - couple of all-rounders could have kept that option. Now, it's given that PAK will play 4 bowlers or even 4 pacers. Another 0; still stuck at 80 for attendance. We can ignore "poor, poor" part here as well, even considering that there was a D/N Test scheduled about a year before the team was selected & 3 Tests were there to show the performance of finger spinners in D/N Test.
3. Amir is a strike bowler - he is not like old Asif, who can bowl 25 overs in a day. Off course he can, but that won't be effective, neither Wahab or Rahat while Sohail is incapable of continuing after 15 overs. To be most effective, this attack can function best, if there is couple of bowlers who can give 60 overs in a 100 overs innings, so that Amir & Sohail/Wahab/Rahat can bowl flat-out for 35-38 overs combined - Yasir is one, who can give 30, may be even 35, but, there is no work horse in the team. They should have picked Hamza at least, who has been bowling well & can bowl 25 tight overs. Now, if AUS doesn't lose 3/4 inside 23-25 overs, it'll be impossible to manage work load with Amir, Wahab, Sohail & Rahat. Another 0, OK, may be 5 because there is Imran - that's 85 out of 100, when 80 was already given for attendance. Here also, we can ignore "poor, poor" part, because this same team is very settled in UAE.
Anyway, I tried my best to explain why the combination picked for AUS, particularly after 2-0 in NZ was poor, but can't explain it to someone who thinks same "stability" on UAE condition is applicable in AUS/NZ - even then the squad is poor - Zulfi should have been there
