I have no idea how anyone would think Amir is captaincy material at this point of his career. He is already struggling to live up to expectations in bowling and I dont understand how saddling him with additional responsibility is going to help anyone. Not to mention the obvious anger in the other senior players. It will be a recipe for disaster whichever way you look at it
I am not suggesting this as a fan boy, neither on Amir's talent. I'll put my explanation - then, you do your own judgement.
First, PAK has to bring a bowler or all-rounder as Captain. The core difference with team India & Pakistan lies in their historical team strategy. India always had been better under batting Captain, as their game is built on solid build-up by batting & then slow burning through disciplined bowling. Apparently, Kapil, Bedi, Kumble should have been great Captains - but it was other way round. For PAK, the team strategy is never built around batsmen - partially for lack of it, but mostly because of the style of cricket the players play.
For a struggling team like PAK, it's difficult for batting Captain; because at the end it takes only one ball for the batsman to fail & his failure is measurable. For a bowling Captain, it's easier to lead struggling sides, because he can remain relaxed - even if he goes for 30 in 3 overs, he can take a break, relax & come back for 2nd spell. Besides, a batsman's performance is measured by runs, for bowlers not necessarily he has to take bag full of wickets to be in team - which makes bowling Captains easier to be automatic choice.
There are few criteria to make a Captain - age, automatic choice, critical role in the team, experience, intelligence & ability to lead from the front. I had several post on this, many of the quotes taken from Benaud, Chappel, Brearly, Greog & Imran's book - won't go though that again.
Now, to be honest, there are not many options left at PCB's hand. Easiest option is to appoint Azhar - why not, we have discussed enough, I won't repeat. Apart from him, actually realistic option is Sarfu - groomed from U19 days, automatic choice & to this PAK side, he is a key star. Only problem is, he s WK in 3 formats & he has few years hidden in his age - making him Test Captain is a very short term solution. MoHa could have been a good option with his old action, even Asif, had he not wasted his career.
Regarding Amir's performance, I don't think, we should look only as the wicket tally - in this pathetic pace attack, he is actually bowling well. International teams don't bat with Afridi mind-set, once your fellow bowlers are wasting new ball & going at 4+, batsmen doesn't go after Amir; for that, he is always economical & actually bowling well. People over hyped him, but he is matching my expectation & he actually makes this PAK side on merit. Regarding his cricket intelligence, I don't think the bar is too high for him - no bowling Captain will set that Gabba field on 11th over of the Test. There could be issues with acceptance - which I do agree; Amir has to manage that. But, if he is accepted as player, he should be trusted as Captain as well. Also, I do think like Misbah, he is mentally tough, can fight it out.
Appointing fast bowler always has a risk associated - injury & proper resting in between matches, for that he'll need a good deputy. But, PAK doesn't have any other option, unless PCB wants to go the same merry go round - Azhar/Sarfraz & within a year same discussion. Honestly, if he was remotely smart, I would have named Yasir first, but he is absolute ...
It's a compromised call, but it's not first time that a player is made Captain from scratch. More than anything else, PAK needs a Captain who fits in to the slot - Arthur can fix the rest. Amir can fail indeed, but the positive side is, if he succeeds (which I back him to do), he can lead this side for 5/6 years - even if Azhar/Sarfu succeeds (which I don't don't back Azhar to do at least), still they have numbers written on their career - 2/3 years max.
Considering everything, if you can find me one player -
1. Under 29 (genuine)
2. All-rounder/bowler
3. Makes team on merit
4. Has minimum skill set to lead from the front in his core department
I'll never, never name Amir for this again.
