I would like to play both Karthik and Dhoni, but if I have to pick one then it will be Dhoni as he is a better wk and has a decent record in the tests .... Karthik had a bad series against Pak, so don't know why r u trying to bring in the stats
.... anyways let's not make this a Dhon vs Karthik, coz both of them are talented with the bat
And why can't we drop one of the big 4? Again thats one of those cliche .... can't drop, no replacement .... by your same logic, it's difficult to drop Dhoni as he has been a gr8 wk for Ind .... we can't replace him on the premise that Karthik is as good as him on the basis of what you saw
As i said the whole excercise revolves around playing the big 4 from 3 to 6, and then fitting things up .... which is a pointless excercise in my opinon and the reason why Ind cricket deserves a few set-backs
