I have a feeling that you are mixing T-20 with Test format, original discussion was about Indian Test Squad. having said that as of now Pant's numbers are pretty solid in Red ball cricket and he's the first choice of Selectors in the 5 day cricket, on the another hand in the shorter format his position are debatable due to recent performance (not a right thread so skipping it)
Dhoni is retired(Test), Dinesh kartik's Test career is finished. @deadley already mentioned what actually happened with Wriddhiman Saha.
