2015 was a very odd Ashes. When the ball swung significantly England won. When the ball didn't swing for long periods Australia compiled heavy first innings scores and won as a result of scoreboard pressure.
Only 6 batters (Root, Rogers, Warner, Smith, Cook and Ali) averaged over 30 in the series. Cook and Rogers are Test match specialists, Warner adapted his method during the series, Smith and Root swapped over as World number one batters and there is a good chance that England's number 8 in this series will open the batting in the next one!
Other than these players, there were a lot of "walking wickets" on show in the series. Especially when either side got the ball to move laterally. As coaches, we have a huge role to play in the development of cricketers who have the skills to cope with balls that swerve in and out and also deck off of the pitch.
This comes in the technical wisdom that we impart on the players and also in the way that we expose the batters to tough conditions and to swinging balls.
Technically, when the ball swings, the feet have a tendency not to move.
Jos Buttler showed this in the last couple of test matches. His only method was to try and save himself with his excellent hand to eye coordination. But even that wasn't enough in tough batting conditions.
So what could Jos do to prepare himself for lateral moving conditions in the future?
