With Jadeja not being used for the last match as a bowler, it would be better to try out Ashwin and drop Jadeja, because like Kaif and Ajay J they cannot be selected on clapping ability or fielding alone.
The performance so far in the series, India let the Oz specialist bats to hand around in the death overs, that resulted in Vinay, Irfan and Yadav leaking runs. With Ashwin a couple of extra wickets the Indian bowling can contain SL to 250 or less.
The approach to batting and strategy has changed since the new guy came up.. We look so much like how England were paper tigers when he was their coach..I dont think the players have issues.. It is the coach..He is trying to change the approach to be his own way which isnt working..
