More than Head Coach, PCT needs 4 qualified specialist coaches. In his short career as fielding Coach, Rixon actually has proved what subject matter experts can do. I feel Arthur's failure to take the team to next level isn't for his own limitation, rather his rigidity to stick with his support staffs. May be the structure IND is following now is way forward and BCB actually has changed their management structure as well. However, for both IND & BD one advantage is that both teams have a settled & capable Captain, but PAK team might go for a Captaincy change after WC - no way Sarfraz is going to remain Captain in 3 formats. Therefore, next PCB's HC has an added job of grooming next Captain as well - probably Babar in ODI & Shan in Test, while Sarfraz can stay as T20 Captain till next or next 2 WCs.
Going by the options, I do think Dean Jones can be a fantastic head coach, because he has been around PAK cricket for few years now, does know the culture there. I still am not sure after like 33 months if Arthur does know his team or adopted country (in terms of cricket) much. Besides, as I wrote for BD cricket that Arthur will be my last pick as HC for a team dominated by spin play either with bat or ball - something applicable for PCT as well as long as UAE is the adopted venue. Dean Jones as HC and PCB is allowing Arthur to be part of PSL, so DJ can do that as well and it's probably better for PCT considering respective squads/performance of IU & KK.
BUT, what PCB needs to sort is the specialist coaches - a qualified Level 3 batting coach from ENG or AUS is MUST. Best I have seen is probably Siddons, Andy Flower and Duncan Fletcher, but DF might be too old now and other 2 might not be interested. Add to that a fast bowling coach who actually knows few things of bowling mechanics and skills - ever since Azhar has taken over, I have read lots of hypes, and the day Faheem Ashraf takes 9 wickets @7/2.5 against ZIM reserves, PP goes through hype - but the last SAF tour by PAK & SRL should open some deluded eyes. May be again a foreigner is the way for fast bowling as well - Ian Pont comes to mind, and there are few really good bowling coaches available, like Heath Streak or Bond. if it has to be a local, I'll go for Kabir Khan.
Next is a spin bowling coach - instead of doosra, tishra, choutha .... what PCT needs is conventional spinners who actually turns the ball, can flight & loop it and has the bowling intelligence of getting a batsman out when he is trying to survive - these T20 spinners are not going to do much in middle overs of an ODI, least said about Test is better - SRL debutante took 8 wickets at Durban!!!!! So, no Saqline - they must pay whatever required to bring back Mushi ..... otherwise try to bring Herath, he'll do wonders with PAK spinners - Sunil Joshi has done great job with Miraz, Naeem & Taijul. Finally a fielding coach - Rixon left, Darren Maddy declined, therefore PCB's reputation isn't that great, but still they can find a top class fielding coach - there are few available. Not sure still available but Fontain, Penny, Mike Young, Woodward ....... can do the job, but one is required. In fact, I tend to believe Grant will do a better job as fielding coach than batting coach.
May be this is my dream set-up
Test Captain: Shan, Deputy - Babar
ODI Captain: Babar, Deputy - Shadab
T20 Captain: Sarfraz, Deputy - Babar
Head Coach (Team Director): Dean Jones
Assistant: Must be a local guy - I like the Peshawar guy (Some Mohammad)
Batting Coach: Jaime Siddons
Fast Bowling Coach: Heath Streak
Spin Bowling Coach: Mushi/Herath
Fielding Coach: J Fontain
CS: YK/Md. Wasim/Bazid Khan
3 different captains didnt work for pak before, and it wasnt successful formula elsewhere..
Always been one captain across both formats has worked for many and all countries... All captains who has won the CWC so far has been the captains across both red and white ball even in this modern era which is also not an exception..
At max 2 different captains can be made with the advent of stress and pressure of playing and captaining three formats of the game, which is also what India trying recently to relax the workload of their captain Kohli..
Since the beginning when Sarfraz was made the test captain, i have said Azhar was the most deserving at that point of time with double and triple centuries to his name as an opener... MA has made biggest blunders in tests for pak, which is removing Azhar as opener, not giving him the test captaincy, playing one spinner in UAE...
Even now, I think Azhar is still the best choice to lead Pak in tests why because he has retired from ODIs so which will make him to concenterate on the only format he is responsible for.. He should go back to opening the innings along with Imam and let shan be number three and Haris be no.4
When it comes to coaches, since not many coaches are available to take the pak job. And also i feel MA can continue even after the CWC and be their till 2023 CWC.. If and when in between, there are poor performances from the team and MA looks clueless, then it is time to find new coach...
But for now there should be a change in bowling coach. Where i feel Akram from PZ should replace Azhar Mahmood... And for Grant flower the position needs to review after the CWC and needs to be changed highly likely.. For now since I cannot see a better option than Babar becomes an automatic selection in other formats, he will be my deputy on all formats..
Test Captain: Azhar ali, Deputy - Babar
ODI Captain: Sarfraz, Deputy - Babar
T20 Captain: Sarfraz, Deputy - Babar
Head Coach (Team Director): Mickey Arthur
Assistant: Does Mickey have one, I'm not sure, if there is then i would take Johan Botha as an assistant and fielding coach
Batting Coach: Julian Wood or Graham Thorpe or Graeme Hick (who is also an excellent slip fielder)
Fast Bowling Coach: Md. Akram
Spin Bowling Coach: Mushi/Herath
Fielding Coach: Johan Botha
If Mickey has to be sacked then my choices for the HC are Tom Moody, Jason Gillespie, Kirsten, Rixon
