India head coach Rahul Dravid admitted to the fact that playing in the Big Bash League 'certainly' helped England players in their emphatic ten-wicket win over India in the semi-final on Thursday but also asserted that if the BCCI allows the players to feature in the foreign leagues, India's domestic cricket would be under threat. England produced a clinical performance in Adelaide as Jos Buttler and co. used their experience of playing in Australia's Big Bash League and in the Indian Premier League to perfection in outclassing India.
