Coming under Indian Olympic Association, whereabouts clause of WADA and general disinterest. Let alone Olympics, we sent a B team to the CWG 1998 and didn’t even send a team at last Asian games.
As I have said in past as well, ICC (in reality BCCI, ECB and CA) need to show intent before any talk of Cricket in Olympics gains momentum. Let them add Cricket to CWG. Let the top players take part in CWG and Asian Games, then and only then they should talk about inclusion in Olympics.
Logistically speaking, with the use of drop-in pitches, a T20 tournament of 8 teams is feasible and not very costly. It brings new audiences and potential medallists from South Asia and Caribbean but there are other sports which are better integrated with Multi-Sports Games.
