This. The batsmen may need some time to get used to the international scene sometimes, but they'll eventually come good if we stick with them imo. More India A tours in foreign conditions might help them get used to conditions earlier too.
It's not the bowling bench strength that's just poor - sometimes the first choice bowlers look like they have no answers. Besides Zaheer, and Harbhajan(sometimes), it doesn't look great. Zaheer seems to not be the same player after injury, but we'll see. While spin is not a major concern for me, with Mishra, Ojha(think he's the best limited overs spinner) and Ashwin besides Harbhajan - and Piyush, who is talented, but still lacking something - it's the pace bowling that needs to be sorted out. It's crazy how we can't even produce one genuinely quick bowler.
