It may be. However who can the batters practice against to make themselves better? Ravi Ashwin is one of the best in the business and our spinners are non league in comparison.
Many sides have gone to places like India and been made to look bang average. Coming in to this series we were on a decent run having beaten average teams like South Africa and Sri Lanka. We are probably 4th or 5th best in the world with the top 3 of India, Australia and NZ streets ahead. The latter 2 I believe would also struggle against this India outfit in these conditions.
