Dravid is an honest person. Do not forget that Dhoni was the deputy of Dravid in ODI matches. This means they were working together in ODI matches. He did not say that he wanted to play in Twenty20 like Ganguly. Ganguly even said that he missed playing in this World Cup. Probably he afraid that Gambhir (another left hander opener)might take his place in ODI also. Dravid is honest enough to understand that Twenty20 is meant for youngsters only.
