IMHO and honestly India's home dominance came to an end because both Ashwin and Jadeja had an off series, especially Ashwin. These 2 stalwarts were the unmoved ingredients in 12 years of home dominance and they were the savior and bailed us out with the bat countless times and with the ball every single time, not this time and it's alright as you can't expect them to carry a team for so long.
If these 2 guys had a satisfactory series with the bat then the result could've been different, there is an inside joke and meme for a reason that Indian real batting starts at 6th,7th, and 8th numbers.
I still don't have a complete trust that India will win this match for sure because the pitch is turning and our batting unit is kind of terrible especially Rohit and Kohli so even if the target is 170 kinda thing I feel India might struggle to chase it down.
Only good thing is Washington is evolving, so in the next couple of years he will be read to fit in the shoes of Ashwin and as I already said they need someone like Pujara to grind the innings and don't expect Kohli to does that job which why he is not playing in his natural attitude since all the players around him are kind of stroke makers so team might want Kohli to play defense but it's not his kind of success in this format.
