Rohit Sharma captain, Pujara dropped; Jaiswal in, Rahane Test vice-captain: Beginning of India's Test revamp?

After the crushing loss to Australia in the World Test Championship final, India has made some big changes to their Test and ODI squads. Yashasvi Jaiswal has made his maiden call-up to India's Test squad for the tour of West Indies. Rohit retains his captaincy for the upcoming two-test series against the West Indies but 105-Test veteran Cheteshwar Pujara has been dropped, while Ajinkya Rahane returns as Rohit's deputy. Does this team give an impression that BCCI has started planning for the future as the new WTC cycle begins?
