I disagree. Most of the players in the current lineup are experienced players(Kishan, Gill, Sky etc) and have played around the world which is why you are stating poor excuses to justify their bad performances.
On the other hand, West Indies performed admirably despite some of the players having little to no experience in any format.
All the players are experienced right but it's only in their own field? Gill,Samson,Ishan Kishan,Sky there are many others who have seen amazing batting in IPL but could not show any innings worth noticing in his West Indies tour. Like Rohit Sharma,Virat Kohli,Jadeja they are yet to become experienced players. On the other hand West Indies players are famous all over the world for their various T20s they have always played well in T20s as a result of which India lost two matches in a row. With an experienced captain the team wins 50% of the matches. I think Hardik Pandya is not able to give 100% of his captaincy there. The 2nd match saw Pooran single-handedly lead his team to victory. No Indian batsman is playing well except Varma. Let's see if India will field with their previous squad in today's match or give chance to new players. If India lose today's match they will have to face the shame of losing the series.
