Virat kholi most runs collector In the world cup history as well as all Indian.
Shami 24 wickets another world class the highest record in the CWC.
Jadeja the best all-rounder and sometimes he greatly backed up batting at number 6/7.
SKY batting well at number 7/8.
In fact, you can tell whether a player should be blamed or not. Since the entire Indian team did not play well on the day of the final, it should be blamed on the entire Indian team, in this case, blaming only two or four players would certainly look spectacular.
The blame should fall on the team, as well as the management. The pitch at Ahmedabad was supportive of spin bowling and still Indian selectors refused to include Ravichandran Ashwin in the playing XI. Ashwin's inclusion would have strengthened their bowling as well as strengthened the lower order batting. For the final match, Kuldeep was the only full-time spinner and that was more like a big handicap for India. Jadeja was supposed to back him up, but he failed in doing that. Also, Indian lower order failed to make any significant contribution with the bat.
Your idea is 100% true and everyone will agree with your idea. If the Indian team management had given importance to the team selection and chosen to bowl on the Ahmedabad pitch, they might not have performed so badly that day. Rahul Dravid's team selection was not wrong, but they should have considered the spin on the pitch that day. Only Virat Kohli, Rohit Sharma, and KL Rahul's contribution was not noticeable that day.
