The two main reasons for early exit for WC are 1). Flat wickets in india 2). inablity to takle pressure
India lost its first match because of its inability to play on bouncy and turning wickets and lost agains srilanka due to failure to tackle pressure situation.
So BCCI should order to prepare bouncy and turning wickets at all test and one-day centers across india And appoint some phycologist who can teach players how to handle pressure situation.
If this two things are implemented , we can avoid humiliating defeats like in WI last yr , SAF this winter and early WC exit...
