On batting i agree but i would argue that even bowling did more than enough in absence of Bumrah, newbies won 2nd match and picked up 20 wickets.
Even in the second match, England was able to score 400 plus in the first innings and close to 300 in the second. India won the match only because of the 269 from Shubman Gill (none of the other batsmen got to a hundred, with Ravindra Jadeja making 89). Siraj picked up 6 wickets in the first innings, but that was after the bowlers allowed England to recover from 84/5 to 387/5. During the second innings from England, again no.9 batsman Brydon Carse was able to score runs quite easily.
