You didn't mention the worst captain of them all -Mohd Yousuf (brilliant batsman though). Apologies to cover_drive for saying that about Moyo ;-)
Harder to judge Pak captains because they operate in a parallel universe to other teams! 1st order of day is dealing with back stabbers - from both in and out of team! lol No home grounds. Expert Media comprises of older players like Shoaib Akhtar and MoYo who are constantly looking to openly even their own personal scores. Board has been spending more time in Supreme Court and with lawyers than anything cricket. For a fair while they didn't have the legal powers to take any decisions!
Misbah - from the start - has the exact opposite team to Ponting. Completely in shatters and limited in offense. Even now top 5 Batsmen are "juniors" and constantly failing. Most of the games he is always playing the rescue role. Over time that will impact your game and thinking too.
Misbah is deemed too defensive for Pakistan standards- they love flamboyant characters in Pak. Even after failing for a decade Afridi is still the biggest hero and the first choice for captain - regularly up voted by media!
When England win hardly anyone complains about Cook being defensive etc but Misbah is bashed regardless every time. Misbah is still Pak' top batsman in all formats and to an outsider the only choice for captain. He is not brilliant but in current scenario ordinary will do!
Misbah has always been a poor captain.
He should have been gone after the farce of the Champions Trophy. Only now has he been blooding in youngsters to the team, too little too late since the World Cup is around the corner.
Also, his captaincy is like from the 90s if not before, it's old fashoined. He himself doesn't lead from the front, slows down the scoring and puts pressure on his partners, I don't think I've seen him set up or finish a game off apart from the test series in Sri Lanka a while back.
Very poor captain and player, he's made Pakistan to be a very predictable and boring team, there's a stat that if he gets out before 40 Pakistan usually win the game.
Dhoni in limited overs though is quite good, considering his poor bowling options, the team seems to do really well in tournaments.
Clarke's got to be the best at the moment.
