Only one week time is allotted for the Indian team to travel to South Africa and get acclimatized. After the three match T20I series, they will be playing a 3-match ODI series against South Africa. It will be interesting to see who will be included in the squad. There are rumors that KL Rahul will be named as the captain and senior players such as Rohit Sharma and Virat Kohli will be rested for this series. I find it regressive. Why stick with KL Rahul again and again? I would have rather preferred someone like Shreyas Iyer as the captain this time.
I think if Pandaya is fit and available for the white ball series (T-20 +ODI) then he'll surely lead the team in T-20, then there is a possibility of him leading in the ODI as well. Fitness is a big issue for Iyer, The dude has a habit of picking injuries out of nowhere so he's a risky bet.
I am not sure about ODI leadership but I don't want to see Rahul becoming the captain of the T-20 and Test team. In fact, selectors should keep him away from the T-20 setup.
