Yeah but this series they've taken 20 wickets as required in each test and arguably kept their team in it. The batsmen, 2 individual innings apart, have been terrible in shot selection and execution. I think India have had two problems in this series, firstly they were not prepared sufficiently for the South African pitches and secondly Kohli is allowed to operate with far too much autonomy. As great a player as Kohli is he needs be careful in letting his aggressive personality blind his decision making, he cannot drop players on a whim and they should really play an extra specialist batsman away from home especially against the 4 man pace attack they are facing.
