I agree with you but there was definitely a change in approach from Smith - maybe it was a team thing as there was a lot of sweeping going on.I don't get why those Jadeja dismissals would send smith down the sweep route though. Those dismissals where completely against his 2017 methodology, feel like he would tried going back more to the 2017 methodology then going further away from it.
When England beat India in 2012/13, we used the sweep alot and used it well.
