India's series against South Africa will be one of the most important tours for Indian cricket not only because of the WTC points at stake but also because the team will undergo a transition phase during this time.
A lot of things have happened simultaneously in the team. While there has been a Cambrian explosion of high-quality cricketers ready to play international cricket, at the same time India doesn't want to let go of their key senior players who still have some cricket left in them.
The thing is, the key senior players, namely - Ajinkya Rahane, Cheteshwar Pujara, and Ishant Sharma haven't been in the best of forms lately which has also led to questions being asked whenever they have an average outing. The demand of them being replaced by a 'deserving' youngster grows louder on each outing.
