India lacks power hitters in T20I, even in the ODIs they seems to be struggling if V.Kolhi or R.Sharma are not there to finish off their innings.
I guess this has been the pattern for India for a long time they are not comfortable chasing down anything above 165 in T20Is, they badly relies on top 3 to consolidate and finish at the same time.
The inclusion of R.Pant is the proof of the same as they lack fire power in their batting they want to induct someone who can give some impetus to the potential score, and I believe M.S. Dhoni is to blame for this because he can neither bat at no. 4 nor he is capable to finish the game with 6s and 4s. Some 1 year or so back I donot think R.Pant was even in the India's plan let alone playing the Test matches, his inclusion is testimony of how Indian team lacks confidence in M.S. Dhoni to push the score at a higher pace.
