Most of those wins you are throwing out here are ODI tournaments. I am not even remotely questioning Dhoni's captaincy in ODI's. I am ONLY TALKING ABOUT HIS TEST CAPTAINCY! Dhoni to me is an ODI legend! I am a massive fan of the guy in ODI's, only next to my love for Sachin Tendulkar. But he has been massively incompetent in test cricket, be it with captaincy or with the bat. No captain would survive a 8-0 whitewash overseas, Dhoni survived it and beyond and is still being part of so many overseas defeats (and that too painful defeats like this) without being questioned at all. He is immovable to the point where you can say he has a monopoly.
And always, overseas wins will be given more weight than home wins due to the challenging conditions. For us always, winning overseas is what matters. Today Saurav Ganguly is considered India's greatest captain ever because he (along with people like Dravid, Laxman, Tendulkar) changed India's fortunes overseas. There have been lot of instances in the past where captains have been sacked after overseas series defeats. Dhoni is a very rare instance where a captain was not sacked even after a 8-0 whitewash. And seeing our results post the retirement of seniors, the margin of defeat has changed but we continue to play/lose badly.
What again are u fixating on the 8-0, two series about 8 months apart and in between the wins at home don't count? Everyone knows the 1 - 3 -15 run overseas, but what about the 11-2-2 run in the same period at home? You are saying sack Dhoni because he cannot win overseas, well which Indian captain has? There was a good run under Dravid, when India won in ENg and NZ, but thats the best it has EVER got for India overseas.
Thats the point, apart from not winning Overseas, which No Ind Captain has done with any great consistency ever anyway ... what wrong has Dhoni done. Still has one of the best home test records, and has won all kind an manner of ODI and T20 tournaments for India
Sack him for doing everything right, apart from having that one failing that thousands have had before him anyway.
