Younis Khan should grow up. captains put up with all kinds of insanity. sure the insanity in the subcontinent is a little more insane than the rest of the world... but even Ponting puts up with ridiculous criticism... you don't see him biatching about the two world cups he's won and all the test series he's won. he continues on more determined than ever to shut up his critics... Wasim put up with the most any Pak captain probably ever has - Younis has seen nothing compared to Wasim. but Wasim was still always willing to take on the challenge because he knew that he was the leader the team needed and responded to.
this is not to say that Dasti is not clinically insane. he clearly is a mental patient. but Younis has a history of not reacting well to any kind of criticism. it's like he walks around with the resignation in his pocket ready to put it in when anything happens that is not to his liking. he clearly knows that he's the only real captaincy candidate and frankly is using it to blackmail Pak cricket. doubt he would be so carefree with the resignation drama if the team had players/leaders of the caliber of Imran and Wasim who could realistically take over the captaincy from him.
if Younis' resignation is accepted, he should not be made captain ever again. and he should also realize that without the captaincy, his spot in the ODI team is pretty shaky.
